Matthew 3:11-12

I baptize you with water so that you will change the way you think and act. But the one who comes after me is more powerful than I. I am not worthy to remove his sandals. He will baptize you with the Holy Spirit and fire. His winnowing  shovel is in his hand, and he will clean up his threshing floor. He will gather his wheat into a barn, but he will burn the husks in a fire that can never be put out.”
