Matthew 5:17-19 states, "Do not hink that I have come to destroy the law or the prophets. I have not come to destroy but to fulfill. For truly I say to you, till the heaven and earth pass away, not one jot or tittle shall in any way pass from the law until all is fulfilled. Therefore whoever shall break one of these commandments, the least, and shall teach men so, he shall be called the least in the kingdom of heaven. But however shall do and teach them, the same shall be called great in teh kingdom of Heaven."
The "problem" with most x-ians is they don't follow the law at all, claiming that lawlessness = grace. Paul said in Romans 6:1-2, "What shall we say then? Shall we continue in sin so that grace may abound? Let it not be! how shall we who died to sin live any longer in it?"
