John 1:20

Now while the people were in a state of expectation and all were reasoning in their hearts about John, as to whether he was the Christ,

He was not the Light, but he came to bear witness about the Light.

“You yourselves are my witnesses that I said, ‘I am not the Christ,’ but, ‘I have been sent ahead of Him.’

“And as John was fulfilling his course, he kept saying, ‘What do you suppose that I am? I am not He. But behold, one is coming after me of whom I am not worthy to untie the sandals of His feet.’
