Matthew 5:17-19

What our saviour said to his followers about the Law.

Matt 5:17 (AV) Think not that I am come to destroy the law, or the prophets: i am not come to destroy, but to fulfil.

Yahshua tells us to not even think he came to destroy the law or prophets, let alone believe it! If you say that he came and abolished the law, then you are saying he came to destroy the Law. That's not what he came to do. The meaning of fulfill here is to "obey"! For instance, if I told my daughter to do something and she did it, then she has "fulfilled", or obeyed my request. Here is an instance of Yahshua fulfilling something:

Matt 8:16 (AV) When the even was come, they brought unto him many that were possessed with devils: and he cast out the spirits with [his] word, and healed all that were sick: 17 that it might be fulfilled which was spoken by Isaiah the prophet, saying, "himself took our infirmities, and bore [our] sicknesses." (Isa. 53:4)
You see, Yahshua fulfilled or "obeyed" the Scripture that was speaking of him. He also obeyed the law. We should do likewise. 18 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.

1Pe 2:21  For to this you have been called, because Messiah also suffered for you, leaving you an example, so that you might follow in his steps.

Now here is a little trick by the translators. They translate the word fulfill here again even though it does not come from the same greek word as the "fulfill" above. They try to get us to believe that since Messiah fulfilled the law, that one jot and one tittle has passed from the law (or been taken away). This greek word is translated "be" 253 times, "come to pass" 82 times and fulfilled 3 times. It is never used in reference to Yahshua fulfilling anything in the Law and prophets. Therefore the meaning of this is that not one iota of the Law will pass away until everything comes to pass. Clearly there is more to come. In Yahweh's coming kingdom, we will then have no need for the Law and prophets because we will have no sinful nature. However, we all have this sinful nature that we must fight and overcome by the power of Yahshua in us. Therefore we still need the Law and prophets to help guide us into the path of righteousness. Many say that we need no law now that we have Yahweh's spirit. But truly, Yahweh's words are spirit and are life. John 6:63 - And surely David had Yahweh's spirit (psalms 51:11) and yet he still looked to the Law for guidance. (psalms 19 and 119)
Matthew 5:19 Whosoever 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 called great in the Kingdom of heaven.
Notice here it says "these" commandments! what are "these" commandments?
The commandments can be found in the law and prophets! They are listed in both Exodus chapter 20 and Deuteronomy chapter 5. Last, but not least, Paul made this statement that one must consider:

Rom 7:12  Wherefore the law is holy, and the commandment holy, and just, and good.
