Let me speak from personal experience to the sinner who does not yet know the joy and freedom of the Lord. Some day, if not already, you will be sharply convicted of sin by the Spirit of God. You may have been full of doubts and quibbles, of ready answers and self-defense, but then you will have nothing to say. You will then have no doubt about the reality of God and the Holy Spirit, and will need no argument to assure you of it; for you will know the voice of God speaking to your soul, and will feel, as did ancient Israel, “Let not God speak with us, lest we die.” Then you will know what it is to be shut up in prison,—in a prison whose walls seem to close on you, not only barring all escape, but seeming to suffocate you. The tales of people condemned to be buried alive with a heavy stone upon them, will seem very vivid and real to you, as you feel the tables of the law crushing out your life, and a hand of marble seems to be breaking your very heart. Then it will give you joy to remember that you are shut up for the sole purpose that “the promise by faith of Jesus Christ” might be accepted by you. As soon as you lay hold of that promise,—the key that will unlock any door in Doubting Castle,—the prison doors will fly open, and you can say, “Our soul is escaped as a bird out of the snare of the fowlers; the snare is broken, and we are escaped.” Ps. 124:7. [Sidenote: Under the Law, Under Sin.] We have just read that the Scripture hath shut up all under sin, that the promise by faith of Jesus Christ might be given to them that believe. Before faith came, we were kept in ward under the law, shut up unto the faith which should afterwards be revealed. We know that whatsoever is not of faith is sin (Rom. 14:23); therefore, to be under the law is identical with being under sin. We are under the law solely because we are under sin. The grace of God brings salvation from sin, so that when we accept God’s grace we are no longer under the law, because we are freed from sin. Those who are under the law, therefore, are the transgressors of the law. The righteous are not under it, but are walking in it. [Sidenote: The Law a Jailer, a Taskmaster.]
