Some things with the passing of time become annulled, like blood sacrifices of animals for the remission of sin, for Christ became our Passover Lamb. But the Ten Commandments give to Moses at the mount have not changed one iota and Jesus taught this. (Matthew 5:17-19). Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. 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. 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.
We know the commandments are still in effect as they are not only spoken of in the Old Testament but also in the new. (Romans 13:8-10). Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
Not only are the ten commandments still in effect, Jesus even gave us a new commandment that will stand out to others that you are His disciple if we do it, and that is to love one another! (John 13:34-35). A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.
13 Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
