Jesus began his ministry by being baptized by John the Baptist and then spending 40 days in the desert, where he was tempted by Satan. He preached the kingdom of God, healed many, and called his first disciples, teaching with authority and performing miracles, while facing opposition from the Pharisees and scribes. Jesus predicted his own death and resurrection, and after entering Jerusalem, he cleansed the temple and taught about faith and prayer. He was betrayed by Judas, arrested, and condemned to death by crucifixion, but on the third day, he rose from the dead, appearing to his disciples and commissioning them to preach the Gospel to the world.
