Matthew 3:11-12

“As for me, I baptize you with water because of [your] repentance [that is, because you are willing to change your inner self—your old way of thinking, regret your sin and live a changed life], but He (the Messiah) who is coming after me is mightier [more powerful, more noble] than I, whose sandals I am not worthy to remove [even as His slave]; He will baptize you [who truly repent] with the Holy Spirit and [you who remain unrepentant] with fire (judgment). [Luke 3:16] His winnowing fork is in His hand, and He will thoroughly clear out His threshing floor; and He will gather His wheat (believers) into His barn (kingdom), but He will burn up the chaff (the unrepentant) with unquenchable fire.”
