Charles Spurgeon Commentary Galatians 3:17

"Now this I say: A covenant confirmed beforehand by God, the law, which came four hundred and thirty years after, doth not disannul, so as to make the promise of none effect." — Galatians 3:17 (ASV)

And this I say, that 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.

Is not that splendid argument? The covenant was made with Abraham that God would bless him and his seed. Now, four hundred and thirty years later, the law was given on Sinai; but that could not affect a covenant made four hundred and thirty years before. The argument proves that the covenant of grace is not affected by any law of rites and ceremonies; no, not even by the moral law itself. The covenant made with Abraham and his seed must stand; the seed signifies those who believe; therefore, the covenant stands firm with Abraham and all other believers.
