I didn’t know he was the one, but when God sent me to baptize with water, he told me, ‘The one on whom you see the Spirit descend and rest is the one who will baptize with the Holy Spirit.’
“I baptize with water those who repent of their sins and turn to God. But someone is coming soon who is greater than I am—so much greater that I’m not worthy even to be his slave and carry his sandals. He will baptize you with the Holy Spirit and with fire.
John answered their questions by saying, “I baptize you with water; but someone is coming soon who is greater than I am—so much greater that I’m not even worthy to be his slave and untie the straps of his sandals. He will baptize you with the Holy Spirit and with fire.
But when the Father sends the Advocate as my representative—that is, the Holy Spirit—he will teach you everything and will remind you of everything I have told you.
(When he said “living water,” he was speaking of the Spirit, who would be given to everyone believing in him. But the Spirit had not yet been given, because Jesus had not yet entered into his glory.)
Some of us are Jews, some are Gentiles, some are slaves, and some are free. But we have all been baptized into one body by one Spirit, and we all share the same Spirit.
