1 Corinthians 3:13-15 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. If any man’s work abide which he hath built thereupon, he shall receive a reward. If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.

Our salvation is not of works, but of grace. But, there are works which are required of the children of God. All will suffer loss, for all have sinned and come short of the glory of God, and continue to do so every day. They are all sinners, there is none righteous. But, our loss is limited by our obedience, for every work of righteousness will remain. Notice that, “if any man’s work abide“, suggests there will be few who have works that survive the test. And then, even more importantly, notice that even those who suffer total loss will be saved. The disobedient, who do no righteousness, will be finally saved because of the work accomplished by Jesus Christ for them. This is true grace, not of works, lest ye should boast.
