Everything we know about the life of Jesus comes from the Bible. Jesus’ name is not mentioned in any other source written during his lifetime. No book written within the lifetimes of people who might have known him mentions him either. (Find out more about this). According to the Bible, Jesus was born during the reign of the Roman Emperor Augustus, about 4 BC. (There is some disagreement about exactly when.) The Bible says he was born in Israel, in the town of Bethlehem. And he grew up near Bethlehem, in Nazareth. When he was about 30, Jesus took to preaching in public like his cousin John the Baptist. That was in the reign of the Roman Emperor Tiberius,
Jesus had many new ideas to talk about. He told people that after the Last Judgment at the end of time they would either go to Heaven or go to Hell. He told people that faith in God, and in Jesus as the son of God, were the most important ways of getting into Heaven. And Jesus said that God no longer wanted animal sacrifices, because Jesus himself was going to be the biggest sacrifice ever. And if you believed in Jesus then his sacrifice would be for you too.
After a few years of preaching, (again according to the Bible) Jesus got in trouble with the Jewish leaders in Israel. They didn’t believe he was the son of God. So they didn’t like him going around telling people that.
The Jewish leaders went to the Roman governor of the province, Pontius Pilate. (His name does appear in an inscription found by archaeologists.) They told Pilate that Jesus was getting too powerful. Pilate was afraid that Jesus might be leading a rebellion against Rome. So he ordered his soldiers to hang Jesus from a cross until he was dead. (This was a normal Roman punishment for criminals.)
