Jesus gave to us water baptism, but was to be unto believers in Him !Sarcasm to follow:
Wasn't it this same Jesus who gave us this baptism? You know, the Deity himself, Second Persona of the Trinity, God and all, the Son of Man in the flesh (incarnate), the Son of God, through Him all things were created, that one and the same Jesus? Besides Jesus' office is that of saving, I won't tell him how to do his job.
End of sarcasm.
Serious inquiry follows:
But what is it about the preached gospel that saves? Is there either a component, reaction or both that must take place in order for Jesus to save a person? If so, what are these things? Also please consider how much or how little of the Gospel message is effective (saves to the uttermost) as you understand things?
End of serious inquiry.
