2 Chronicles 19

If you see your neighbor committing sin, take care not to dwell exclusively on his sin, but think of the many things he has done and continues to do rightly. Many times, by examining the whole and not taking the part only into account, you will find that he is better than you. God does not examine humans according to the part, for he says, "I come to gather together their works and thoughts." Furthermore, when he rebuked Josaphat for a sin committed in an unguarded moment, he mentioned also the good he had done, saying, "But good works are found in you."

Do not doubt that this duty of ours is a part of religion because God, "with whom there is no iniquity," whose power is supreme, who not only sees what each one is but also foresees what he will be, who alone cannot err in his judgment because he cannot be deceived in his knowledge, nevertheless acts as the Gospel expresses it, "He makes his sun to rise on the good and bad, and rains on the just and unjust."

Another particle of the perfection of the fear of the Lord consists in perfect promptitude of obedience. Hence in the book of Chronicles: "Let the fear of the Lord be with you, and do all things with diligence": as if to say: do not be sluggish or negligent, because it is written in Ecclesiastes: "He who fears God neglects nothing." If I believed that a thief was going to enter my chamber and carry off my treasure, I would not leave the window open. You must always fear God, because he who "keeps the whole law but offends in one point has become guilty of all."
