The beginning of the gospel of Jesus Christ, the Son of God. As it is written in Isaiah the prophet,Behold, I send my messenger before your face, who will prepare your way, the voice of one crying in the wilderness: ‘Prepare the way of the Lord, make his paths straight,’”John appeared, baptizing in the wilderness and proclaiming a baptism of repentance for the forgiveness of sins. And all the country of Judea and all Jerusalem were going out to him and were being baptized by him in the river Jordan, confessing their sins. Now John was clothed with camel’s hair and wore a leather belt around his waist and ate locusts and wild honey. And he preached, saying, “After me comes he who is mightier than I, the strap of whose sandals I am not worthy to stoop down and untie. I have baptized you with water, but he will baptize you with the Holy Spirit.” Mark 1:1-8 (ESV)
John the Baptist was the prophet who ushered in the new era of the Messiah. His message was a call to genuine repentance that leads to a changed life. He was humble before the almighty Christ. John foretold that Jesus the Messiah would give the Holy Spirit to His followers to enable them to walk in His ways.
