Dr. Couch, Acts 22:16 seems to say that water baptism “washes” away our sins. How do you answer?
To understand 22:16 you have to start with 3:19. 3:19 reads, speaking to the nation of Israel: “Repent therefore and return, that your sins may be wiped away (blotted out, ‘exaleipho’), …” Repent and return are both Second person Plurals, Aorist Imperatives. Or, “All of you repent and all of you return [back to God] [with the result that] your sins will be blotted out (wiped away).” “Wiped away” is an Aorist Passive Infinitive. Or, “Your sins will be acted upon, blotted away, by God”—“They are to be acted upon by the Lord. He will cause them to be gone!” This is based on their repentance and their returning to God! Of course the message they are to believe in is the fact that “Christ should suffer” [for you], and this “He has thus fulfilled” (v. 18).
