You are baptizing people, then you see the Son of God approach for you to baptize Him. Remember you have been preaching to people a baptism of repentance for the remission of sins, and as people have come to you, they confessed their sins.
Yet, you see the Son of God in line for baptism just like anyone else. What would you do?
As you know, that happened to John,
“Then Jesus came from Galilee to John at the Jordan to be baptized by him. And John tried to prevent Him, saying, ‘I need to be baptized by You, and are You coming to me?’” (Matthew 3:13–14).
John answered just as any of us would probably have done. What else could he say?
