A man named John was sent from God. He came for testimony, to testify to the light, so that all might believe through him. He was not the light, but came to testify to the light.

So they asked him..."Who are you, so we can give an answer to those who sent us? What do you have to say for yourself?" He said: "I am the voice of one crying out in the desert, make straight the way of the Lord."

What I say to you, I say to all: Watch!"
