According to the Canonical Gospels, the ministry of Jesus began when Jesus was around 30 years old, and lasted a period of 1–3 years. In the biblical narrative, Jesus' method of teaching involved parables, metaphor, allegory, sayings, proverbs, and a small number of direct sermons. This was the first coming of Jesus; as most Christian denominations believe in a Second Coming when Jesus will return to the earth to fulfill aspects of Messianic prophecy, such as the general Resurrection of the Dead, the Last Judgment of the dead and the living and the full establishment of the Kingdom of God on earth (also called the "Reign of God"), including the Messianic Age.
