The Law was given by Moses (John1:17) and its purpose was “… to keep people from having excuses, and to show that the entire world is guilty before God” according to Romans 3:19 (NLT). Romans 5:20 NLT also gives another wonderful reason why the law was given; “ God’s law was given so that all people could see how sinful they were…” Paul, further in Galatians 3:19 (NLT), asks this question in a direct way by saying “Why, then, was the law given? It was given alongside the promise to show people their sins. But the law was designed to last only until the coming of the child who was promised.
God gave his law through angels to Moses, who was the mediator between God and the people.” Pure and perfect as the law is, it was never meant to be kept.
Because the law could not make us righteous, God sent Jesus to take the punishment of our sins so that we can be acceptable. We did not deserve this because we never earned it! It is unmerited favor, Grace! Now that we are saved by God’s grace, we live by that Grace. That Grace has a name, His name is Jesus Christ. New Testament Christians live by grace, not the demands of the law. This is the life we now adore, Jesus Christ the Son of God.
The law was brought so that man realizes that he cannot keep it but needs help to do so. And that help is Jesus Christ. Nothing in the Bible says the law was given to be kept. It also had an end date, “until Christ”. Galatians 3:24-25 “So the law was our guardian until Christ came that we might be justified by faith. 25Now that this faith has come, we are no longer under a guardian.” This last phrase is of importance. It simple says “we cannot base our believing under the requirements of the Law of Moses, but Jesus” Romans 6:14 puts a seal to this, it says (NIV) “For sin shall no longer be your master, because you are not under the law, but under grace.” “Christ is the end of the law for righteousness to everyone that believes.” (Rom. 10:4) . Now that Christ is there, the LAW is obsolete.
What the law of Moses was expected to do, Christ did by dying for the ungodly and giving us Righteousness as a gift received by faith in Jesus. It is the righteousness of faith that now matters, not the righteousness brought by obedience to the law (Phil. 3:9). This is why understanding and living by grace, and not the law, is key in the life of any believer after the resurrection of Jesus. The law came to an end, and Jesus lives forever more.
