Matt.5:18 says “For verily I say unto you, till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.” Jesus’ death was the fulfillment of all so now the law could pass away. Remember that while Jesus was here on earth during his earthly ministry it was still the Old Testament era. Jesus came to usher in THE NEW! Matt.5:19 says “Whosever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be great in the kingdom of heaven.” Jesus was speaking to the Jews who were under the Mosaic Law at this time. Hebrews 9:16, 17 says “For where a testament is, there must also of necessity be the death of the testator. For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.” Jesus had to die before the New Testament could be activated! Hebrews 10:4-9 says “For it is not possible that the blood of bulls and of goats should take away sins. Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: In burnt offerings and sacrifices for sin thou hast had no pleasure. Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God. Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law: Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second. The Old Law or Testament has been taken away. The phrase “He taketh away” in the Greek means to abolish, to put to death. Jesus nailed the Law to the cross at his death. It was abolished there. So the four gospels are basically still the Old Testament. It would make since then that Matthew 5:19 would speak on “breaking the least commandments”. John 16:12 says “I have yet many things to say unto you, but ye cannot bear them now.” What Jesus is saying here will be crucial to our understanding of what the Holy Spirit HAS COME TO DO!
