The law was still in force during the life of Christ. It was fulfilled and ceased to be in force at the death of Jesus because the law was replaced by the law of salvation for which he died.
* "Do not think that I came to destroy the Law or the Prophets... Till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled. Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great..." Mat. 5:17-19
Has Heaven and Earth passed away yet? Didn't think so... But just in case... Jesus said quite plainly in the first part that he had NO intention of destroying Moses's law whatsoever.
