A Little Encouragement Before We Begin

You don’t need to know everything about Christianity to get started. You don’t need to have all the answers or understand every part of the Bible.

Come with an open mind, take your time and explore each topic at your own pace.

We’re here to help you discover what Christians believe, understand the message of Jesus and explore what it means to have a personal relationship with God.

Let’s begin discovering Christianity together!

Have you ever wondered what Christianity is really all about? Perhaps you’ve heard people talk about God, Jesus, the Bible or going to church, but you’re not entirely sure what it all means. Maybe you have questions about who Jesus really was, why He died, what Christians believe about salvation, or how you can begin a relationship with God.

You might even be curious about Christianity but unsure where to start.

You’re not alone. Many people have questions about faith, and exploring those questions is a wonderful place to begin.

Christianity is more than attending church, following religious traditions or trying to live a good life. At its heart, Christianity is about knowing God personally, discovering His love for you and understanding what He has done through Jesus Christ.

The Christian message is one of love, forgiveness, hope and new beginnings. It tells the story of a God who loves humanity so much that He made a way for us to know Him.

Whether you’re completely new to Christianity, exploring your beliefs or simply looking for answers, this guide will introduce you to the foundations of the Christian faith.

Let’s start at the beginning.

1. What Is Christianity All About?

Christianity is a faith centred on the belief that there is one God who created the world and everything in it. Christians believe that God is loving, holy, just and deeply interested in having a relationship with the people He created.

Unlike the idea that we must somehow earn God’s love through good behaviour or religious achievements, Christianity teaches that God’s love is a gift.

The Bible explains that every human being has been created in God’s image (Genesis 1:27). This means that every person has value, dignity and purpose.

God created humanity to know Him, love Him and enjoy a relationship with Him. However, the Bible also explains that something went wrong.

Understanding sin and our separation from God

The Bible describes sin as anything that goes against God’s character and His good purposes. It includes things such as dishonesty, selfishness, hatred, pride and wrongdoing.

Sin isn’t simply about making mistakes or failing to be perfect. It describes the brokenness that affects our relationship with God, with other people and even with ourselves.

Romans 3:23 says:

“For all have sinned, and come short of the glory of God.”

Christians believe that everyone has sinned and that nobody can make themselves right with God simply by being good enough.

But here’s the wonderful news: God hasn’t abandoned humanity.

Rather than leaving us separated from Him, God made a way for us to be forgiven and restored through Jesus Christ.

This is the heart of Christianity: God loves us, Jesus came to save us, and through Him we can have a new relationship with God.

2. Who Is Jesus and Why Does He Matter?

At the centre of Christianity is a person: Jesus Christ.

You may have heard His name many times, perhaps in conversations, at Christmas or Easter, or through references in books, films and music. But who exactly is Jesus?

Christians believe that Jesus is the Son of God, fully divine and fully human. He came into the world to reveal God’s character, teach people about His kingdom and make a way for humanity to be reconciled to God.

Jesus was born in Bethlehem, grew up in Nazareth and lived approximately 2,000 years ago.

During His earthly ministry, He taught people about God’s love, forgiveness, compassion, truth and grace.

He welcomed those who were rejected by society, showed kindness to the poor, healed the sick, forgave sinners and challenged religious hypocrisy.

His life demonstrated what God’s love looks like in action.

What did Jesus teach?

Jesus taught that loving God and loving others are central to living a life of faith.

When asked about the greatest commandments, He answered:

  • Love the Lord your God with all your heart, soul and mind.
  • Love your neighbour as yourself.

(Matthew 22:37–39)

Jesus also taught about forgiveness, humility, generosity, prayer and trusting God.

One of His most well-known teachings is the Golden Rule:

“Do unto others as you would have them do unto you.” (Matthew 7:12)

His message wasn’t simply about following a list of religious rules. He wanted people to understand that God desires a genuine relationship with them, one that transforms their hearts and influences how they live.

Why is Jesus so important to Christianity?

Jesus is important because Christians believe He is much more than a good teacher or a historical figure.

He is the Saviour through whom people can receive forgiveness, experience God’s grace and have eternal life.

Without Jesus, the central message of Christianity would not exist. His death and resurrection are the foundation of the Christian faith.

3. What Is the Bible and What Does It Teach?

The Bible is the central sacred text of Christianity. Christians believe it is God’s Word and that it reveals His character, His purposes and His plan for humanity.

If you’re new to Christianity, the Bible can seem like a big and complicated book. However, its overall message is a beautiful story of God’s relationship with humanity.

The Bible contains 66 books, divided into two main sections.

The Old Testament

The Old Testament contains 39 books and describes God’s relationship with humanity before the coming of Jesus.

It includes:

  • Creation: How God created the heavens, the earth and humanity.
  • The Fall: How sin entered the world and affected humanity’s relationship with God.
  • God’s promises: How God made promises to people such as Abraham.
  • The history of Israel: The story of God’s chosen people and their relationship with Him.
  • The Psalms and wisdom books: Teachings about worship, prayer, wisdom and living a life that honours God.
  • The prophets: Messages calling people back to God and pointing towards the coming Messiah.

The Old Testament helps us understand God’s character, His faithfulness and the background to the arrival of Jesus.

The New Testament

The New Testament contains 27 books and focuses on Jesus Christ, the beginning of the Christian church and the teachings of the apostles.

It includes:

  • The four Gospels: Matthew, Mark, Luke and John, which tell us about Jesus’ life, teachings, miracles, death and resurrection.
  • Acts: The story of the early Christian church and how the message of Jesus spread.
  • The letters: Writings that explain Christian beliefs and offer guidance on how to live as followers of Jesus.
  • Revelation: A book containing prophetic visions about God’s ultimate victory and the fulfilment of His purposes.

Where should you start reading the Bible?

If you’ve never read the Bible before, you don’t need to begin at page one and work your way through.

A wonderful place to start is the Gospel of John.

John introduces Jesus, explains who He is and explores why believing in Him matters.

You could also explore:

  • Luke: A detailed account of Jesus’ life and ministry.
  • Matthew: An introduction to Jesus’ teachings and the Kingdom of God.
  • Psalms: Beautiful prayers and expressions of faith, hope and worship.
  • Proverbs: Practical wisdom for everyday life.

Remember, you don’t need to understand everything immediately. Take your time, ask questions and allow yourself to discover what the Bible teaches.

4. Why Did Jesus Die on the Cross?

One of the most important questions in Christianity is why Jesus died.

If Jesus was the Son of God and lived a perfect life, why did He allow Himself to be crucified?

To understand this, we need to return to the Christian understanding of sin.

The Bible teaches that sin separates humanity from God. Because God is holy and just, sin cannot simply be ignored. Yet God is also loving and merciful, and He desires to restore our relationship with Him.

This is where Jesus comes in.

Christians believe that Jesus willingly gave His life on the cross as a sacrifice for the sins of humanity.

His death made forgiveness possible and demonstrated the incredible depth of God’s love.

Romans 5:8 explains:

“But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.”

Think about what this means.

God didn’t wait for humanity to become perfect before showing His love. Jesus came because we needed Him.

The cross reminds Christians that forgiveness is not something we can earn. It is something God offers through His grace.

What does the cross mean for us today?

The cross represents:

  • Love: God’s extraordinary love for humanity.
  • Forgiveness: The opportunity to receive forgiveness for our sins.
  • Grace: God’s undeserved kindness towards us.
  • Reconciliation: The opportunity to have our relationship with God restored.
  • Hope: The promise that our past does not have to define our future.

The cross is central to the Christian message because it shows that God’s love is greater than our failures.

5. Why Is the Resurrection of Jesus So Important?

The story of Jesus doesn’t end with His death.

Christians believe that three days after His crucifixion, Jesus rose from the dead.

This event is known as the resurrection, and it is one of the most important foundations of Christianity.

According to the New Testament, Jesus’ tomb was found empty, and He appeared to His followers after His resurrection.

The resurrection demonstrated that Jesus had overcome death and confirmed His identity and victory over sin.

In 1 Corinthians 15:17, the apostle Paul explains the importance of the resurrection to Christian faith.

Without it, the Christian message would have no foundation. But because Jesus rose again, Christians believe that death does not have the final word.

What does the resurrection mean for Christians?

The resurrection gives Christians hope in several ways:

  • New life: Through Jesus, we can begin a new life with God.
  • Victory over sin: We are no longer defined by our past mistakes.
  • Hope beyond death: Christians believe that those who belong to Christ will experience eternal life.
  • Confidence in God’s promises: The resurrection assures believers that God is faithful and powerful.

Easter celebrates this wonderful truth: Jesus is alive!

The resurrection is a reminder that even when life feels difficult, God can bring hope, restoration and new beginnings.

6. What Is Salvation and How Can You Be Saved?

You may have heard Christians talk about being saved, receiving salvation or accepting Jesus.

But what does salvation actually mean?

In Christianity, salvation means being rescued from sin and restored to a right relationship with God through Jesus Christ.

It is God’s gift of forgiveness, grace and eternal life.

The Bible teaches that salvation is not something we can earn through good works, religious activities or trying to be a perfect person.

Instead, it is received through faith in Jesus.

Ephesians 2:8–9 explains:

“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.”

Let’s break that down.

Grace

Grace means receiving God’s kindness and forgiveness even though we haven’t earned it.

You don’t have to prove that you’re good enough for God to love you.

Faith

Faith means trusting in God and believing in Jesus Christ.

It involves more than simply knowing that Jesus existed. It means placing your trust in Him and recognising Him as your Saviour and Lord.

Repentance

Repentance means recognising that you have sinned and choosing to turn away from wrongdoing and towards God.

It involves a change of heart and a willingness to allow God to guide your life.

Repentance doesn’t mean that you will never make another mistake. It means that you genuinely want to follow God and grow in your faith.

Receiving salvation

The Bible teaches that whoever calls upon the name of the Lord will be saved (Romans 10:13).

Salvation is an invitation open to everyone, regardless of their background, past experiences or mistakes.

You don’t need to have everything figured out before coming to God.

You can come to Him honestly, just as you are.

7. How Can You Begin a Relationship With God?

One of the most beautiful things about Christianity is that God doesn’t simply want people to know about Him. He invites them to know Him personally.

You don’t need to be in a church building to speak to God. You don’t need special words, a perfect understanding of the Bible or years of religious experience.

You can begin by simply talking to Him.

This is called prayer.

Prayer is communicating with God. You can thank Him, ask questions, share your worries, seek guidance or simply tell Him what is on your heart.

Here are five simple ways to begin growing closer to God.

1. Start talking to God through prayer

You don’t need complicated language. Speak honestly and openly.

You might begin by thanking God for His love and asking Him to help you understand who He is.

2. Start reading the Bible

Set aside a few minutes each day to read a passage.

The Gospel of John is an excellent starting point because it focuses on who Jesus is and why He came.

3. Learn to trust God

Faith is a journey. As you learn more about God’s character and His promises, you can begin to trust Him with different areas of your life.

4. Find a welcoming Christian community

Connecting with other Christians can help you learn, ask questions and grow in your understanding of faith.

You could visit a local church, attend a Bible study or speak with a trusted Christian who can help guide you.

5. Allow your faith to influence how you live

Following Jesus involves more than believing certain things. It means learning to love others, forgive, show kindness, practise humility and make choices that honour God.

You won’t become perfect overnight, and Christianity doesn’t promise a life without difficulties. But it offers the opportunity to grow in your relationship with God, knowing that His grace is there along the way.

8. What Does It Mean to Be a Christian?

Being a Christian means believing in Jesus Christ, trusting Him as your Saviour and choosing to follow Him.

It is not about pretending to be perfect or having all the answers.

Christians are ordinary people who recognise their need for God’s love, forgiveness and guidance.

Following Jesus is a lifelong journey of learning, growing and becoming more like Him.

As you develop your faith, you may begin to notice changes in the way you think, respond to others and approach life’s challenges.

You may become more aware of the importance of forgiveness, compassion, patience, kindness and generosity.

The Bible describes these qualities as the fruit of the Spirit (Galatians 5:22–23).

Being a Christian doesn’t mean that life will always be easy. You will still face difficulties, questions and moments when your faith feels uncertain.

But Christianity teaches that you don’t have to face life alone. God promises His presence, guidance and love.

9. A Simple Prayer to Begin Your Journey With God

If you’ve been reading this and feel that you would like to know God, you might be wondering what to say.

You can begin with a simple, honest prayer.

Prayer isn’t about saying the perfect words. It’s about coming to God sincerely.

Here is an example of a prayer you may find helpful:

A Prayer to Begin a Relationship With God

Dear God,

Thank You for loving me and for wanting me to know You.

I recognise that I have made mistakes and that I need Your forgiveness. Thank You for sending Jesus to die for my sins and rise again so that I can have a relationship with You.

Jesus, I believe in You. I want to learn more about You, understand Your Word and follow Your ways.

Please forgive me, guide me and help me grow in faith. Teach me to trust You, love others and live a life that honours You.

Thank You for Your grace, Your mercy and Your unconditional love.

I want to begin this journey of knowing You.

In Jesus’ name,

Amen.

This prayer is not a formula that earns God’s acceptance. Christians believe salvation comes through God’s grace, received through genuine faith in Jesus.

10. Where Do You Go From Here? Your Next Steps in Exploring Christianity

Discovering Christianity doesn’t have to happen all at once.

You don’t need to understand every Bible passage, know every Christian teaching or have an answer to every question before you begin.

Give yourself time to explore, learn and grow.

Here are a few practical ways to continue your journey:

Read the Gospel of John. Start with one chapter a day and pay attention to what it teaches about Jesus.

Ask questions. If something doesn’t make sense, don’t be afraid to explore it. Asking questions is a healthy part of discovering what you believe.

Make time for prayer. Even a few minutes of honest conversation with God can be a meaningful starting point.

Explore the life of Jesus. Learn about His teachings, the miracles He performed, the people He met and the message He shared.

Connect with a Christian community. Find a welcoming church or Bible study where you can learn and ask questions without feeling pressured.

Most importantly, remember that Christianity is about a relationship with God, not simply learning religious information.


Discover the Love, Hope and Truth of Christianity

Perhaps you started reading this because you were curious about Christianity. Perhaps you have questions about Jesus, the Bible, salvation or what it means to have faith.

Whatever brought you here, one of the most important things to understand is this:

Christianity is ultimately about God’s love for you and His invitation to know Him through Jesus Christ.

God’s love isn’t something you have to earn. His forgiveness isn’t reserved for people who have lived perfect lives. And you don’t have to have everything figured out before you begin exploring faith.

Jesus came to offer forgiveness, hope, new life and the opportunity to have a restored relationship with God.

John 3:16 captures the heart of the Christian message:

“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”

This is the invitation at the heart of Christianity: to discover who Jesus is, understand what He has done and experience the love of God for yourself.

Your journey of faith can start today, one question, one prayer and one step at a time.
