Who Is Jesus? What the Bible Says and Why It Matters

Summary: Jesus of Nazareth was a Jewish teacher who lived in the land of Israel in the first century and was crucified by the Romans around AD 30. Christians believe He is the Son of God, fully God and fully human, who lived a sinless life, died on the cross to pay for the sins of the world and rose from the dead three days later. The Bible presents Him as the only way to a restored relationship with God, offered freely to anyone who trusts Him.

Scripture quotations in this guide are from the King James Version (KJV).

Almost everyone has an opinion about Jesus. Some see Him as a wise moral teacher. Some think of Him as a prophet, one voice among many. Others have grown up with stained-glass pictures and Christmas carols but have never really asked who He claimed to be. And some are quietly curious, wondering whether there is something to this figure who still shapes calendars and conversations two thousand years after He walked dusty roads in Galilee.

Whatever brought you here, this page is meant to be an honest starting point. We will look at what history tells us, what Jesus said about Himself, why His death and resurrection sit at the centre of the Christian faith, and what any of it has to do with your life on an ordinary Tuesday.

Did Jesus really exist?

It surprises some people to learn that the existence of Jesus is not seriously disputed among historians, whether they are Christian or not. The debate is about who He was, not whether He was.

Outside the New Testament, the Roman historian Tacitus, writing in the early second century, mentions "Christus," who was executed under Pontius Pilate during the reign of the emperor Tiberius. The Jewish historian Josephus, writing in the late first century, refers to Jesus and to "James, the brother of Jesus, who was called Christ." Neither writer was sympathetic to Christianity, which makes their passing references all the more interesting.

Then there are the four Gospels themselves: Matthew, Mark, Luke and John. These were written within living memory of the events they describe, and Luke opens his account by saying he carefully investigated everything from the beginning, drawing on eyewitnesses (Luke 1:1-4). Paul's letters, some written barely twenty years after the crucifixion, already speak of Jesus' death and resurrection as the core of what believers had been taught.

So the historical Jesus is on firm ground. He was born in Bethlehem, grew up in the small town of Nazareth, worked as a carpenter and, around the age of thirty, began a public ministry of teaching and healing that lasted roughly three years. That ministry ended with His execution in Jerusalem during the Passover festival.

What did Jesus say about Himself?

Here is where things get interesting. Jesus did not present Himself as one teacher among many. In the Gospel of John especially, He makes a series of striking claims that begin with the words "I am."

• "I am the bread of life: he that cometh to me shall never hunger" (John 6:35).
• "I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life" (John 8:12).
• "I am the good shepherd: the good shepherd giveth his life for the sheep" (John 10:11).
• "I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live" (John 11:25).
• "I am the way, the truth, and the life: no man cometh unto the Father, but by me" (John 14:6).

To a first-century Jewish audience, "I am" carried enormous weight. It echoed the name God gave Himself when He spoke to Moses from the burning bush: "I AM THAT I AM" (Exodus 3:14). When Jesus told a crowd, "Before Abraham was, I am" (John 8:58), they picked up stones to throw at Him. They understood exactly what He was claiming.

Jesus also forgave sins, something His listeners knew only God could do (Mark 2:5-7). He accepted worship. He called God His own Father in a way His hearers understood as "making himself equal with God" (John 5:18). And He spoke of Himself as the One who would judge the world. These are not the words of someone content to be remembered as a good example.

This is why the writer C. S. Lewis famously argued that calling Jesus merely a good teacher is the one option He does not leave open. If His claims were false, He was not a good teacher at all. If they were true, He is far more than one.

Is Jesus God?

Christians believe that Jesus is fully God and fully human. That sounds like a contradiction at first, so it is worth explaining carefully.

The Gospel of John opens with a remarkable passage: "In the beginning was the Word, and the Word was with God, and the Word was God... And the Word was made flesh, and dwelt among us" (John 1:1, 14). The "Word" is Jesus. John is saying that the eternal Son of God, who existed before creation, took on a real human body and lived a real human life.

That means Jesus got tired and hungry. He wept at the grave of His friend Lazarus. He felt the full weight of fear in the garden of Gethsemane. At the same time, He calmed storms with a word and raised the dead. After the resurrection, the disciple Thomas, who had doubted, fell at His feet and said, "My Lord and my God" (John 20:28). Jesus did not correct him.

The church later summed up this teaching in the creeds, which describe Jesus as "Very God of very God" who "was made man." This belief is shared by nearly every Christian church in the world. You can read more about these shared convictions in our guide to what all Christians agree on.

Why did Jesus have to die?

The cross sits at the centre of Christianity. To understand why, we have to start with a problem the Bible describes plainly: "For all have sinned, and come short of the glory of God" (Romans 3:23).

Sin is not only about breaking rules. It is about a broken relationship. We were made to know and love God, yet every one of us has gone our own way. That breaks things around us too, in families and in whole societies. And because God is just, sin cannot simply be ignored. A judge who shrugs at wrongdoing is not a good judge.

The good news, which is what the word "gospel" means, is that God Himself stepped in to pay the cost. "But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us" (Romans 5:8). Jesus, who had no sin of His own, took our place. The penalty we deserved fell on Him, so that the forgiveness He deserved could be offered to us.

Isaiah, writing centuries before Jesus was born, described it with startling accuracy: "But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed" (Isaiah 53:5). That last line is printed on one of our most-loved shirts, By His Stripes We Are Healed, because it captures the heart of the story in a single sentence.

Did Jesus really rise from the dead?

Paul did not treat the resurrection as an optional extra. He wrote, "if Christ be not raised, your faith is vain; ye are yet in your sins" (1 Corinthians 15:17). Christianity rises or falls on this event.

The New Testament records that Jesus was buried in a borrowed tomb, and that on the third day the tomb was found empty. Over the following weeks He appeared to many people: to Mary Magdalene in the garden, to the disciples behind locked doors, to two travellers on the road to Emmaus and, according to Paul, to more than five hundred people at once, most of whom were still alive when Paul wrote (1 Corinthians 15:3-8).

Several facts are hard to explain without a real resurrection. The disciples went from hiding in fear to boldly preaching in the same city where Jesus had been executed. Many of them suffered and died rather than deny what they had seen. The first witnesses to the empty tomb were women, whose testimony carried little legal weight in that culture. If someone were inventing the story, they would hardly have chosen them. And James, Jesus' own brother, who did not believe in Him during His ministry (John 7:5), became a leader of the church in Jerusalem after the resurrection.

The resurrection is the reason Christians speak of hope rather than wishful thinking. It means death is not the end, that Jesus' claims were vindicated and that the forgiveness offered on the cross is real.

What does grace mean for you?

Grace is God's undeserved kindness. It is receiving what we could never earn. "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" (Ephesians 2:8-9).

This is where Christianity differs from almost every other way of thinking about God. Most systems tell us to climb our way up through effort and goodness. The gospel says God came down. We do not clean ourselves up to be accepted. We are accepted, and then God begins the lifelong work of making us new.

John wrote that from Jesus' fullness "have all we received, and grace for grace" (John 1:16). Wave after wave of grace, one gift on top of another. Our Grace Upon Grace tee is a small reminder of that overflowing generosity.

Grace also brings freedom. Jesus said, "If the Son therefore shall make you free, ye shall be free indeed" (John 8:36). Free from guilt that has no answer. Free from the exhausting need to prove yourself. Free from the fear of death. Free to live and love with an open heart.

How can I begin a relationship with Jesus?

If something in you is stirring as you read this, you do not need to wait until you understand everything. Faith begins with a simple response of trust. The Bible puts it like this: "That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved" (Romans 10:9).

Becoming a Christian is not about joining a club or adopting a set of rules. It is about turning to Jesus, admitting your need for Him and trusting Him as your Saviour and Lord. If you would like to take that step, you can pray something like this, in your own words:

Lord Jesus, I believe You are the Son of God. I know I have sinned and I cannot fix that on my own. Thank You for dying on the cross for me and for rising again. I turn from going my own way and I put my trust in You. Forgive me, and lead my life from today. Amen.

If you prayed that, we would love to hear from you through our contact page. The next steps are to find a local church, start reading the Gospel of John, tell a Christian friend and begin to pray.

Frequently asked questions

Is there evidence Jesus really existed?

Yes. Historians across belief systems accept that Jesus was a real person who was crucified under Pontius Pilate. Besides the New Testament, the Roman historian Tacitus and the Jewish historian Josephus both refer to Him.

Is Jesus God?

Christians believe Jesus is fully God and fully human. He claimed divine titles such as "I am" and forgave sins. The Gospel of John describes Him as the eternal Word who "was made flesh, and dwelt among us" (John 1:14).

Why does God allow suffering if Jesus loves us?

The Bible does not hide from this question. Jesus Himself suffered, which means God is not distant from our pain. Christians believe suffering is part of a broken world that God has promised to heal. We explore this in depth in hard questions about Christianity.

What does it mean to be saved?

To be saved means to be rescued from the penalty and power of sin and restored to a relationship with God. It is received by faith in Jesus, not earned by good works, and it begins a new life that continues forever.
