Today, we jump back into our study in Galatians 3:20 where it says, “Now a mediator is not a mediator of one, but God is one.” The very idea of a mediator implies that there are two parties involved. In the given of the Law, it was God and the People with Moses playing the mediator. However, when God made the covenant with Abraham, there was only one party; Himself. We see this in Genesis 15 in that God actually placed Abraham asleep and made the covenant with Himself and Abraham had nothing to do with it. In other words, God would not rely on Abraham keeping his end of the deal for Him to fulfill the covenant. It is what we call an unconditional covenant in the Bible. A conditional covenant requires both parties to comply while an unconditional only requires one.
The same can be said of the promise that Christ has given to us in salvation. It was between Christ and God who are one and the same. Paul said in 2 Corinthians 5:18-19, “And all things are of God, who hath reconciled us to himself by Jesus Christ…To wit, that God was in Christ, reconciling the world unto himself…” It is not conditional upon us keeping the Law but in Christ already doing it for us. What a deal!
Notice v.21, “Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.” The Law could not give life in that it only pointed out the sinfulness of mankind.
Notice v.22, “But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.” Again, the Law could not save, only the promise that was given to Abraham that looked forward to the Seed (Jesus) could save and our faith in that promise.
On that note, I sometimes hear people say that the folks in the Old Testament were saved by keeping the Law. A thousand times, NO! They could not keep the Law. If they could have, Jesus’ death on the cross was in vain. On the contrary, those in the Old Testament were saved by their faith in looking forward to Jesus and we are saved by our faith in looking back at Jesus!
