John came baptising in the wilderness and preaching a baptism of repentance for the remission of sins. Then all the land of Judea, and those from Jerusalem, went out to him and were all baptised by him in the Jordan River, confessing their sins. Mark 1:4-5

Now after John was put in prison, Jesus came to Galilee, preaching the gospel of the kingdom of God, and saying, “The time is fulfilled, and the kingdom of God is at hand. Repent, and believe in the gospel.” Mark 1:14-15
