Galatians 2:21 English Standard Version (ESV) I do not nullify the grace of God, for if righteousness[jusification] were through the law, then Christ died for no purpose.
Let us skip over the fact that no one has ever been able to keep all the law and that sin is still present in mankind. Knowing that does not explain the purpose of the law. Here in Galatians 2:21 we find the purpose of the law.
If man could keep the law perfectly he was justified to stand before the living God. That we might call a right standing or righteousness. Since this verse ties directly into the death of Christ then it is reasonable to assume that His death changed the demands of the law for righteousness sake.
Righteousness or a right standing before God is no longer associated with keeping the law. Now that is good news. It is not all the good news because it is a little more complicated than saying I no longer have to keep the law.
What was it about Christ’s death that made this the game changer?
Hebrews 7:26-28 English Standard Version
26 For it was indeed fitting that we should have such a high priest, holy, innocent, unstained, separated from sinners, and exalted above the heavens. 27 He has no need, like those high priests, to offer sacrifices daily, first for his own sins and then for those of the people, since he did this once for all when he offered up himself. 28 For the law appoints men in their weakness as high priests, but the word of the oath, which came later than the law, appoints a Son who has been made perfect forever.
The word of the oath came after the law and replaced the law as a means of justification before God.
As we said before, the good news is more complicated than God speaking to us. Now we have to find this oath that replaced the law and what that means to us.
