JHN 1:33

33 I myself did not know [previously] that he [was the Messiah]. However, [God] sent me to baptize people with water, [people who said they wanted to turn from their sinful ways. While I was doing that], God told me, ‘The man on whom you will see my Spirit descend and remain is the one who will put the Holy Spirit within you [(pl) to truly change your lives].’
