In regard to Acts 22:16, Jamison, Fausset, and Brown Commentary makes not of the importance of the Greek in Ananias' statement. When Ananias tells Paul to "arise, be baptized, wash away your sins, calling on the name of the Lord," the tense of the last command is literally "having called" (aorist middle participle). "Calling on [epikalesamenos] --- 'having (that is, after having) called on,' referring the confession of Christ which preceded baptism." [Jamison, Fausset, and Brown Commentary, vol. 3 pg. 160]. Kenneth Wuest picks up on this Greek nuance and translates the verse as follows: "And now, why are you delaying? Having arisen, be baptized and wash away your sins, having previously called upon His Name." (Acts 22:16, Wuest's Expanded NT).
Paul had already believed in Christ when Ananias came to pray for him to receive his sight (Acts 9:17). It also should be noted that Paul at the time when Ananias prayed for him to receive his sight, he was
filled with the Holy Spirit (Acts 9:17)--this was
BEFORE he was water baptized (Acts 9:18). Verse 17 connects his being filled with the Spirit with the receiving of his sight. We know that he received his sight prior to his baptism.

No scripture is to be interpreted in isolation from the totality of scripture. Practically speaking, a singular and obscure verse is to be subservient to multiple and clear verses, and not vice versa.
In Acts 2:38, "for the remission of sins" does not refer back to both clauses, "you all repent" and "each one of you be baptized," but refers only to the first. Peter is saying "repent unto the remission of your sins," the same as in Acts 3:19. The clause "each one of you be baptized" is parenthetical. This is exactly what Acts 3:19 teaches except that Peter omits the parenthesis.
*Also compare the fact that these Gentiles in Acts 10:45 received
the gift of the Holy Spirit (compare with Acts 2:38 -
the gift of the Holy Spirit) and this was BEFORE water baptism. (Acts 10:47)
In Acts 10:43 we read
..whoever believes in Him receives remission of sins. Again, these Gentiles received
the gift of the Holy Spirit - Acts 10:45 -
when they believed on the Lord Jesus Christ - Acts 11:17 - (compare with Acts 16:31 -
Believe on the Lord Jesus Christ and you will be saved) BEFORE water baptism - Acts 10:47. This is referred to as
repentance unto life - Acts 11:18.
*So, the only logical conclusion
when properly harmonizing scripture with scripture is that faith in Jesus Christ "implied in genuine repentance" (rather than water baptism) brings the remission of sins and the gift of the Holy Spirit (Luke 24:47; Acts 2:38; 3:19; 5:31; 10:43-47; 11:17,18; 15:8,9; 16:31; 26:18).
*Perfect Harmony*
