John 1:23

23 "I'm thunder in the desert: 'Make the road straight for God!' I'm doing what the prophet Isaiah preached."

John 1:23 In-Context

21 They pressed him, "Who, then? Elijah?" "I am not." "The Prophet?" "No."

22 Exasperated, they said, "Who, then? We need an answer for those who sent us. Tell us something - anything! - about yourself."

23 "I'm thunder in the desert: 'Make the road straight for God!' I'm doing what the prophet Isaiah preached."

24 Those sent to question him were from the Pharisee party.

25 Now they had a question of their own: "If you're neither the Messiah, nor Elijah, nor the Prophet, why do you baptize?"
