Luke 3:16-17

16John knew what they were thinking. He said to them, ‘I baptize you with water. But someone else is coming soon. He is much greater than I am. I am not good enough even to undo his shoes for him. This other person will baptize you with the Holy Spirit and with fire.

17He is like a farmer that brings the wheat home from his field. He uses a special tool to throw the wheat up in the air. He does this to make the wheat seeds separate from what remains. Then he cleans his yard. He carefully stores all the seeds to keep them safe. But he burns everything else in a great fire that nobody can put out.’
