Frankly, I sin daily. There are sins of commission and sins of ommission. Ever think something of someone else that is not good? Presto, you are guilty...
Mat 5:21 Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
Mat 5:22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
Mat 5:23 Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee;
Mat 5:24 Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.
Mat 5:25 Agree with thine adversary quickly, whiles thou art in the way with him; lest at any time the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison.
Mat 5:26 Verily I say unto thee, Thou shalt by no means come out thence, till thou hast paid the uttermost farthing.
