God, too, is One, the same, always, and hence the law is not due to a change of the divine mind. The law does not give life at all. If it did, and could impart righteousness, then it might be said to be opposed to the promises of righteousness by faith. But none became righteous by the law. The Scriptures place all under sin that the promise should be to them only who believe through Christ.
All hope is in the gospel.
Kept under the law. Before the faith was revealed we were confined under the law, as it were in prison, in a state of preparation for the faith that was to be revealed. Wherefore the law was our schoolmaster. There we are justified by faith. After that faith is come.
