For if the inheritance is of the law, it is no more of promise: but God gave it to Abraham by promise.
All Commentaries on Galatians 3:18 Go To Galatians 3
Cornelius a Lapide
AD 1637
If the inheritance be of the law. If our heritage of righteousness be of the law of Moses, then it is not of the promise. But this is false, for God promised this righteousness to Abraham and to his seed, which is Christ. If it is of the promise of Christ, then it is through faith in Christ, and not through the law of Moses, that all nations are to be blessed.
