Christians sometimes ask “Do the 10 commandments apply to us, or were they just for the Israelites?” The answer is no they do not apply to us, and yes they do!
A summary of the Sinaitic Law is “Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind; and thou shalt love thy neighbour as thyself” (Matthew 22:37-40). Jesus kept, and fulfilled, the Law Covenant by his death. By willingly sacrificing himself so that he should become man’s redeemer (which only he could do as he was the only perfect man since Adam), he was fulfilling the Law which declares that all under it must love God more than they love themselves, and that therefore they would so delight to do God’s will that they would gladly sacrifice their own will, and even their own life. It is declared that Jesus gave up his life joyfully – “I delight to do thy will, O my God: yea, thy law is within my heart” (Psalms 40:8).
Jesus said, “Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil” (Matthew 5:17). The old Sinaitic Law Covenant was fulfilled by Jesus, and is therefore no more in effect. The Apostle Paul said, “In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away” (Hebrew 8:13). Paul also said “Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. But after that faith is come, we are no longer under a schoolmaster” (Galations 4:24-25).
The New Covenant, or Testament, has not yet gone into effect, so far as the world is concerned. The Law associated with the New Covenant will be the same unchanging Law of God, which declares divine opposition to sin, and divine favour and blessing for the righteous. This Law will be in effect during the Millennial age, when allowances will be made for mankind’s imperfections as they are gradually restored to human perfection. Thus it is written “This is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people: … and their sins and their iniquities will I remember no more” (Hebrews 8:10-12; Jeremiah 31:33-34). (This will be part of the “restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began” - Acts 3:21). The New Covenant is a covenant of forgiveness, blessing and restitution.
So the Law Covenant has been fulfilled and cancelled by Jesus and the New Covenant will be in operation during the Millennial age, but what of the interim? Is there any covenant in operation, and is there any law connected with it?
During the interim Gospel age God is selecting the members of the New Creation (the body of Christ), and a covenant is now in force, and it has a law. The Apostle Paul tells us that the Law “was added because of transgressions, till the seed should come to whom the promise was made” (Galatians 3:19). Therefore the Law Covenant given at Sinai was an addition to a previous covenant, and looking back we see that the Abrahamic Covenant was the original one, and that it had stood for 430 years before the Law Covenant was added - “the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect” (Galatians 3:17).
Therefore we see that when our Lord Jesus fulfilled the Law Covenant it left the original Abrahamic Covenant, just as it was before the Law was added, and this is the covenant under which the New Creation is being developed. The Abrahamic promise or Covenant was that “in thee and in thy seed shall all the families of the earth be blessed” (Genesis 28:14). The Apostle explained that this seed refers to Christ - “Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ” (Galatians 3:16), and added, “And if ye be Christ's, [if you become members in particular of the body of Christ] then are ye Abraham's seed, and heirs according to the promise” (Galatians 3:29).
Thus Christians are not under the Sinai or Law Covenant, so what law are we under? The Apostle said “For sin shall not have dominion over you: for ye are not under the law, but under grace” (Romans 6:14). However, this does not mean that we can willingly disobey the Sinaitic Law. When we became Christians we repented of our sinful ways, meaning we regretted them and changed direction, turning away from them (Strong’s concordance describes ‘repent’ as meaning “to change one's mind for better, heartily to amend with abhorrence of one's past sins”). Therefore, having turned away from our sinful ways, we should be trying to not sin, and as disobeying the Law covenant would be a sin we should be trying to obey the Law Covenant, even if we are no longer condemned under it if we fail to keep it completely.
When we consecrated our lives to God, we declared our love for God and his righteousness, and we became bound by the Law of Love. Our hope according to God’s promises is to become adopted sons of God (“he predestined us to be adopted as his sons through Jesus Christ, in accordance with his pleasure and will”, Ephesians 1:5, NIV), which means that we need to develop God likeness, and God is love. “He that loveth not knoweth not God; for God is love” (1 John 4:8).
Jesus said, “Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets” (Matthew 22:37-40). He also said “If ye love me, keep my commandments” (John 14:15), and “the word which ye hear is not mine, but the Father's which sent me” (John 14:24). So if we love God and Jesus we should try to obey God’s commandments and laws. “For this is the love of God, that we keep his commandments: and his commandments are not grievous” (1 John 5:3).
Therefore, having been redeemed from condemnation due to sin, we should now be continually striving to live according to God’s righteous laws (even though we may not be able to succeed completely while still living in our imperfect human bodies). As the Apostle Paul said, “What then? Are we to sin, because we are not under the law but under grace? Of course not!” “We died to sin: how can we live in it any longer?” “We know that our old humanity has been crucified with Christ, for the destruction of the sinful self, so that we may no longer be slaves to sin, because death cancels the claims of sin. But if we thus died with Christ, we believe that we shall also live with him, knowing as we do that Christ, once raised from the dead, is never to die again: he is no longer under the dominion of death. When he died, he died to sin, once for all, and now that he lives, he lives to God. In the same way you must regard yourselves as dead to sin and alive to God, in union with Christ Jesus. Therefore sin must no longer reign in your mortal body, exacting obedience to the body’s desires. You must no longer put any part of it at sin’s disposal, as an implement for doing wrong. Put yourselves instead at the disposal of God; think of yourselves as raised from death to life, and yield your bodies to God as implements for doing right.” “When you were slaves of sin, you were free from the control of righteousness. And what gain did that bring you? Things that now make you ashamed, for their end is death. But now, freed from the commands of sin and bound to the service of God, you have gains that lead to holiness, and the end is eternal life. For sin pays a wage, and the wage is death, but God gives freely, and his gift is eternal life in union with Christ Jesus our Lord” (Romans 6:15,2,6-13,20-23 - REB).
Some people do not understand this and they quote 1 John 3:9 in order to accuse others of not being true Christians – “Whosoever is born [begotten] of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born [begotten] of God”. They think this means that if you commit just one sin, then you cannot be a true Christian, failing to understand that no Christian is completely righteous (Romans 3:10, Psalms 14:2-3) or perfect, and will not be until their resurrection. In the meantime we struggle to be overcomers of the temptations of the flesh, and the world, and Satan, and though we sometimes fail we must never give up trying, nor give up the desire to be righteous. Though we cannot yet be perfect in our thoughts, words and actions, we can have a desire to be perfect. “But if I do what I do not desire, it is no more I working it out, but sin dwelling in me” (Romans 7:20 - MKJV).
It went into "effect" when Christs' blood poured out of his body!!! Blood ratified a covenent in the OT.
