According to the Bible through the prophet Isaiah someone will prepare the way of the Lord.
This was fulfilled by John the Baptist. According to John 1:23 John the Baptist said I am the voice of one crying in the wilderness, Make straight the way of the Lord.
Further in John 1:29 The next day John saw Jesus coming unto him and said, Behold the Lamb of God which take away the sin of the world.
Also in John 1:34 John said and I saw and bare record that this is the Son of God.
