Look to yourselves, that we do not lose those things we worked for, but that we may receive a full reward. 2 John 1:8
If anyone’s work which he has built on it endures, he will receive a reward. 1 Corinthians 3:14
If anyone’s work is burned, he will suffer loss; but he himself will be saved, yet so as through fire. 1 Corinthians 3:15
