According to the accounts recorded in the Holy Injil, John the Baptist was a cousin of Jesus the Messiah and was a great forerunner of the Messiah, as foretold in the prophecy of Isaiah seven centuries before the birth of Jesus and John.  Isaiah wrote,   "A voice of one calling: 'In the desert prepare the way for the LORD; make straight in the wilderness a highway for our God.'" (Isaiah 40:3 NIV)

John said, "After me will come one more powerful than I, the thongs of whose sandals I am not worthy to stoop down and untie.  I baptize you with water, but he will baptize you with the Holy Spirit." (Mark 1:7-8 NIV)

On one occasion, John the Baptist saw Jesus coming toward him.  He said, "Look, the Lamb of God, who takes away the sin of the world!"  (John 1:29 NIV)
