Mark 1:3-5

3“a voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him.’ ” Isaiah 40:3 4And so John the Baptist appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins. 5The whole Judean countryside and all the people of Jerusalem went out to him. Confessing their sins, they were baptized by him in the Jordan River.
