Reverence is a feeling of profound awe and respect and often, of love. Those who revere God at least wont sin due to the fear of His judgment and punishment. If they achieve the deeper level of reverence, they wont sin because they dont want to hurt Gods heart because they love Him. When Joseph served as a servant to Potiphar, an Egyptian officer, Potiphars wife tried to seduce him. But he refused saying, "How then could I do this great evil and sin against God?" In the same way, we can never do the things God hates if we love Him.
