And anyway
In christianity salvation is free and you can not lose it, so if you were saved, you're going to heaven anyway now even if you don't believe, but only you know if you were saved or not, based on 1 John 5:13
.
1 John 5:13
These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.

But you're going to lose rewards at the judgement seat of Christ
Keep in mind these letters are written to christians, so when it says "we must all", it is talking to saved people:
2 Corinthians 5:10
10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.
.
1 Corinthians 3:13-15
13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
14 If any man's work abide which he hath built thereupon, he shall receive a reward.
15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
