Do you think that the law can help you or save you? Let the apostle Paul give you one word as to this: "We who are Jews by nature, and not sinners of the Gentiles, knowing that a man is NOT justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ that we might be justified by the faith of Christ, and NOT by the works of the law, for by the works of the law shall no flesh be justified," (Gal. 2:15, 16).
How then can God justify a guilty sinner? On the ground of the finished work of His own blessed Son on the cross, and of the simple faith on the sinner's part in His own Son and the work of His Son.
Understand this, "As many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them" (Gal. 3:10). Failure on one point brings me in guilty of all, as says the Scripture, "For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all" (James 2:10).
If you are going to have blessing it must be on the ground of faith, not works. We are shut up to mercy. Christ has hung on a tree, and He has taken the curse for every believer. Trust the blessed Savior now and the blessing is yours.
