Mark 1:2-8

As it is written in Isaiah the prophet: “ Behold, I send My messenger ahead of You, Who will prepare Your way;  The voice of one crying in the wilderness,

‘ Make ready the way of the Lord, Make His paths straight.’ ”  John the Baptist appeared in the wilderness preaching a baptism of repentance for the forgiveness of sins. And all the country of Judea was going out to him, and all the people of Jerusalem; and they were being baptized by him in the Jordan River, confessing their sins. John was clothed with camel’s hair and wore a leather belt around his waist, and his diet was locusts and wild honey.  And he was preaching, and saying, “After me One is coming who is mightier than I, and I am not fit to stoop down and untie the thong of His sandals.  “I baptized you with water; but He will baptize you with the Holy Spirit.”
