"Christ returns to be judged for rewards" - is the following what you are referring to ? 1 Cor 3:13-15 :- 13Every 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. 14If any man's work abide which he hath built thereupon, he shall receive a reward. 15If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. 2 Cor 5:10 :- 10For 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.
