I'm not a law-keeper, but I still haven't found a single piece of evidence -- in the Gospels -- that Jesus ever told us to stop keeping the Law. Should we rely solely on what Paul said?
Jesus said, “Are you still lacking in understanding also? Do you not understand that everything that goes into the mouth passes into the stomach, and is eliminated? But the things that proceed out of the mouth come from the heart, and those defile the man. For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, slanders. These are the things which defile the man; but to eat with unwashed hands does not defile the man.”
MATTHEW 15:16-20 NASB
But He said to them, “Have you not read what David did when he became hungry, he and his companions, how he entered the house of God, and they ate the consecrated bread, which was not lawful for him to eat nor for those with him, but for the priests alone? Or have you not read in the Law, that on the Sabbath the priests in the temple break the Sabbath and are innocent? But I say to you that something greater than the temple is here. But if you had known what this means, ‘I desire compassion , and not a sacrifice ,’ you would not have condemned the innocent. For the Son of Man is Lord of the Sabbath.”
MATTHEW 12:3-8 NASB
This is the essence of the law and How Jesus approached and taught about the law.
The dietary laws brushed aside for the law of the heart, and the Sabbath day being under Jesus because he is Lord of the Sabbath and that the priests in the temple don't break the Sabbath because they are in the temple, but Christ is greater than the temple. What does this mean to him who is in Christ who is both greater than the temple and Lord of the Sabbath?
I think Jesus clearly taught that the "law" was coming to an end, because he fulfills the law. As the law was a foreshadow of Christ.
