The LORD is well pleased for his righteousness’ sake; he will magnify the law, and make it honourable. Isa 42:21
Many teach that Jesus came to abolish the law. Did He?
Bible says he came to magnify the law and make it honorable.
How did He magnify it?
26Verily I say unto thee, Thou shalt by no means come out thence, till thou hast paid the uttermost farthing. 27Ye have heard that it was said by them of old time, Thou shalt not commit adultery: 28But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. 21Ye have heard that it was said of them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment: 22But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire. Matthew 5
Also it says He made it honorable.
17Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. 18For 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. 19Whosoever 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. Matthew 5:17-19
(REMEMBER WHOEVER BREAK ONE OF THESE COMMANDMENTS AND TEACH MEN TO DO SO SHALL BE CALLED THE LEAST IN THE KINGDOM OF GOD)
Some say to fulfill is to cease it from existence but please see the below verses to see how Jesus fulfills all righteousness.
13Then cometh Jesus from Galilee to Jordan unto John, to be baptized of him.
14But John forbad him, saying, I have need to be baptized of thee, and comest thou to me? 15And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered him. Matthew 3:13-15
Finally how to get eternal life:
25And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life? 26He said unto him, What is written in the law? how readest thou? 27And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. 28And he said unto him, Thou hast answered right: this do, and thou shalt live. Luke 10:25-28
