Galatians 3:12 - Coke's Commentary on the Holy Bible

And the law is not of faith:— As the Apostle shews here, that there was no obtaining life by the law, without an immaculate obedience; faith, which is used here in opposition to it, must signify a firm belief of the promise of God, and acting according to it, in a dependance upon Christ only for righteousness and salvation; which is the way of justification and salvation revealed by the gospel.
