God establishes a covenant with Noah, his sons, and all living creatures after the flood, promising never to destroy the earth with water again. The sign of this covenant is the rainbow. Jesus suffers and dies to save both the righteous and unrighteous, preaching to spirits in prison. After being tempted in the desert for 40 days, Jesus proclaims that the kingdom of God is at hand and calls people to repentance and faith in the gospel.
