(21-24) If the Law was thus inferior to the promise, does it therefore follow that it is contrary to it? By no means. The Law could not indeed give life; it could not justify, or place in a state of righteousness. Its real result was rather to place all men in a state of sin. But by so doing it prepared the way for the fulfilment of the promise in all who put faith in Christ. The Law was a close and strict, yet salutary, discipline to make us fit for faith in Christ.
