What must i do to be saved (delivered from my sin and its consequences) ?
If we are believers then Acts 2: 37- 39 will tell us what we must do to be saved. Now when they heard this, they were pierced to the heart, and said to Peter and the rest of the apostles, "Brethren what shall we do?" And Peter said to them, "Repent, and let each of you be baptized in the name of Jesus Christ for the forgiveness of your sins, and you shall receive the gift of the Holy Spirit. For the promise is for you and your children, and for all who are far off, as many as the Lord our God shall call to Himself." (Acts 2: 37- 39)
Believers are already saved and don't need to be told what they must do to be saved. In Acts 2:37, their "belief" at this point was mental assent that Jesus was the Messiah and they were guilty of crucifying Him. *That is not saving belief yet.
They still lacked trust and reliance in Christ alone for salvation and that's why they still needed to repent and place their faith in Christ alone for salvation.
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*
If we are non-believers, then Acts 16: 30, 31 will tell us what we must do to be saved. and after he brought them out, he said, "Sirs, what must I do to be saved?" And they said, "Believe in the Lord Jesus, and you shall be saved, you and your household." Acts 16: 30, 31)
*Notice that Paul said,
"Believe in the Lord Jesus Christ, and you shall be saved.." and
not believe in the Lord Jesus Christ
and get water baptized and you shall be saved.
We are all saved through the grace of our Lord Jesus, in the same way as they also are. (Acts 15: 11)
Yes, by grace through faith, not works. Acts 15:7 - And when there had been much dispute, Peter rose up and said to them: “Men and brethren, you know that a good while ago God chose among us, that by my mouth the Gentiles should
hear the word of the gospel and believe. 8 So God, who knows the heart,
acknowledged them by giving them the Holy Spirit, just as He did to us, 9 and made
no distinction between us and them,
purifying their hearts by faith.
