We must consider how Jesus distinguishes between destroying the law and fulfilling the law. It, by His own words here, is not destroyed, however we are no longer condemned by it because we have obtained mercy.
Taking into consideration all of the writings on this subject, we now have the law written upon the tablets of our Hearst, in being new creaturas by the Holy Spirit.
With the law written upon our hearts we know it is merciful, and we know it is just. Even so, we are not Jesus, Yeshua, and we do, by the nature of being in the flesh, tend to counter a law now and then, but we do not live in sin.
Yes we are saved by mercy and grace from God, but we are instructed not to disobey God's commandments……..
If we obey the commandment of worship of our Maker, we will not ignore His wisdom when we learn from Him We weere once children of darkness but now we are come to the light. We were once children of disobedience but we are converted to obey our Lord.
We are warned not to teach against the least of the laws by Jesus, Yeshua, and in Revelation we are taught to obey God's commandments, not to mention the warnings in the letters of Joh..
Is hearing Jesus, Yeshua, and doing His teaching a burden...according to Him it is easy and gives us peace.
