The arrival of Jesus was known by John the Baptist. He baptized Jesus in the Jordan River. During the baptism, the Spirit of God, like a dove, came down upon Jesus, and the voice of God was heard. According to the Bible, the Spirit led Jesus into the desert where he fasted for 40 days. There, he resisted the Devil's temptations. Then Jesus went into Galilee, settled in Capernaum, and began to preach about the Kingdom of God. He was about 30 years old.
