1 Corinthians 15:1-4
Now, brothers, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain. For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures,
They key point in there is "By this gospel you are saved, if you hold firmly to the word I preached to you."
Notice that salvation is conditional - What do you think it means by "holding firmly to the word?"
Let me add this:
But this is how God fulfilled what he had foretold through all the prophets, saying that his Christ would suffer. Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord
It's through repentance (asking for forgiveness and trying to stop that behavior) that the salvation from faith in Christ's sacrifice is applied to us.
