The Gospel of John begins by announcing that God's Word, which brought all things into being, became flesh in Jesus of Nazareth. During his ministry, Jesus reveals the power of God by performing seven miraculous signs, including turning water into wine, healing the sick, and raising the dead. In his preaching he identifies himself as the bread of life, the light of the world, and the good shepherd. Through his crucifixion, Jesus lays down his life, giving God's love to the world. By rising from the dead he shows that those who believe in him have everlasting life.
