The Pharisees were legalists, and Jesus told them to do it right, but He didn't say to forsake the the law, as the person that started this thread is trying to teach. Jesus told the Pharisees to observe what the law was REALLY all about in truth. Reject this truth and reject grace simultaneously. Grace is not an adversary of the truth in the law of God. You actually think that there are 2 different God's, One that gives grace, and the other that gives the law? Get real!!!
Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone. Matthew 23:23
Those that reject even a jot or tittle of the law are just as hypocritical as the Pharisees that Jesus confronted. This is truth, and we will like it or hate it.
If the world hate you, ye know that it hated me before it hated you. John 15:18
