John 1:27

27 It is he who is coming after me; I am not good enough to undo his shoes.

John 1:27 In-Context

25 And they put this question to him, saying, Why then are you giving baptism if you are not the Christ, or Elijah, or the prophet?

26 John's answer was: I give baptism with water; but there is one among you of whom you have no knowledge;

27 It is he who is coming after me; I am not good enough to undo his shoes.

28 These things took place at Bethany on the other side of the Jordan, where John was giving baptism.

29 The day after, John sees Jesus coming to him and says, See, here is the Lamb of God who takes away the sin of the world!
