I've always had the mind set that since an infant can't make a free will choice the principles involved in infant baptism must. And as we can not choose repentance for another soul the only purpose would be for that set of parents through this sacrement upon their child, are making a public covenant with God that they will raise that child in a Godly house and teach it to live under Godly teachings. This in due time will give to the child an awareness of the need to make that choice themselves and thus "repent and be baptized. . ."
May God continue to Bless you all.
"And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him: And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased."
John didn't sprinkle or pour so I think I will have to go with the method Jesus took.
