Life and ministry of Jesus
The ministry of Jesus, according to the account of the Gospels, falls into a pattern of sectarian preachers with devoted disciples. After being baptized by John the Baptist, Jesus preached for a period of one to three years in the early 1st century AD. Jesus' method of teaching involved parables, metaphor, allegory, sayings, proverbs, and a small number of direct sermons such as the Sermon on the Mount. His ministry was ended by his execution by crucifixion at the hands of the Roman authorities by demand of the Jews in Jerusalem.
Christians believe that three days after his death, Jesus rose bodily from the dead. Early works by Jesus' followers document a number of post-resurrection appearances and the resurrection of Jesus formed the basis and impetus of the Christian faith. His followers wrote that he appeared to the disciples in Galilee and Jerusalem and that Jesus was on the earth for 40 days before his ascension to heaven and that he will return to earth to fulfil aspects of Messianic prophecy, such as the resurrection of the dead, the last judgment and the full establishment of the Kingdom of God.
The main sources of information regarding Jesus' life and teachings are the four canonical gospels, and to a lesser extent the Acts of the Apostles and the Pauline epistles. Christianity's theology is largely founded and based on one central point found in these Gospels: that Jesus died and rose from death as God's sacrifice for human sins.
