Faith AND repentance are required for salvation.
Jesus Himself plainly said He came to call sinners unto repentance, and warned that unless we repent, we shall perish:
Luke 5:30 And the Pharisees and their scribes grumbled at his disciples, saying, “Why do you eat and drink with tax collectors and sinners?”
Luk 5:31 And Jesus answered them, “Those who are well have no need of a physician, but those who are sick.
Luk 5:32 I have not come to call the righteous but sinners to REPENTANCE.”
Luke 13:3 No, I tell you; but unless you REPENT , you will all likewise perish.
In addition to the fact that Jesus came to call sinners unto repentance, He also said after His resurrection that repentance for the remission of sins must be preached to all nations:
Luke 24:46 And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
Luke 24:47 And that REPENTANCE and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
Plus, as Jesus was about to ascend, He told the apostles in Matthew 28:19 to make disciples of all men, teaching them all He commanded them, which would include teaching the need to repent of sins or perish.
And other scriptures will confirm that repentance - which includes asking God to forgive our sins - is required for salvation, alongside faith.
John wrote that we must confess our sins, to have them forgiven:
1Jn 1:9 If we confess our sins, he is faithful and just to forgive us oursins, and to cleanse us from all unrighteousness.
Paul preached both faith AND repentance is necessary, not just faith:
Act 20:20 Andhow I kept back nothing that was profitable unto you,but have shewed you, and have taught you publickly, and from house to house,
Act 20:21 Testifying both to the Jews, and also to the Greeks, REPENTANCE toward God, AND faith toward our Lord Jesus Christ.
Repentance towards God, and faith towards Jesus: both are needed, and are separate - repentance is not automatically part of faith., said Paul.
And Paul continues to confirm that repentance AND faith are required
Act 26:19 “Therefore, O King Agrippa, I was not disobedient to the heavenly vision,
Act 26:20 but declared first to those in Damascus, then in Jerusalem and throughout all the region of Judea, and ALSO to the Gentiles, that they should repent AND turn to God, performing deeds in keeping with their REPENTANCE.
In one text, Paul preached repentance toward God AND faith towards Jesus - in another that we should repent AND turn to God.
Then in Acts 3:19, we are told to repent and be converted for the forgiveness of our sins:
Act 3:19 Repent therefore, and be converted, that your sins may be blotted out
In that text, repentance clearly precedes conversion and forgiveness of our sins - and as 1 John 1:9 makes plain, repentance includes confessing our sins to God, for their forgiveness.
Albert Barnes explains this about Acts 3:19:
Sin cannot be pardoned before man repents of it. In the order of the work of grace, repentance must always precede pardon. Of course, no man can have evidence that his sin is pardoned until he repents. Compare Isa 1:16-20; Joe 2:13”.
Repentance must always precede pardon.
Peter also told those 3,000 who were added to the church that day, to repent, and be baptized, in Acts 2:38.
It is unequivocally clear that repentance is separate from faith; that repentance is needed, alongside faith, as part of being saved ; and that repentance includes asking God to forgive our sins, and not just changing our minds about sin.
