If the heathen have received the law in their hearts, why is the Sabbath not found, as well as other precepts? Rom. 2:14, 15. The scripture itself reads, "For when Gentiles that have not the law do by nature the things of the law, these, not having the law, are the law unto themselves; in that they show the work of the law written in their hearts, their conscience bearing witness therewith, and their thoughts one with another accusing or else excusing them." The great principles of the law summed up in the Old Testament, and by our Saviour approved, are, supreme love to God and equal love to our fellow men. The heathen that has that to the fullest sense of his capacity certainly will be excused by his own conscience. Yet during that very time he might have a multitude of wives. During that very time he might be doing other things that conventionalities of this age would not permit, that greater light from the Word of God would condemn, just as did Abraham, just as did Jacob. The law written in their hearts is primarily not complete knowledge, but complete principle of doing right. God has expressed this in 2 Chron. 16:9: "For the eyes of the Lord run to and fro throughout the whole earth, to show Himself strong in the behalf of them whose heart is perfect toward Him." That is what God asks—the perfect affection, the perfect heart. The one dominant thing that moves the man, is his affections, his love. He may know scarcely anything; he may have seen but one ray of light from the throne of God, but that ray of light dominates his life, and the man who yields himself to that ray of light is accepted of God. But the man who may have a knowledge of all the Ten Commandments of God's law, and yet yields himself to one sin, however small it may seem, turns away from the light, and will be rejected. It is not knowledge that saves us—that is, mental knowledge, intellectual knowledge; it is the life of God in the soul which comes by yielding ourselves absolutely to all that we see. The heathen who has that in his heart, will yield to all the light that comes to him, to the sixth commandment, the seventh commandment, the eighth commandment, the fourth commandment. It is to him then only a matter of revelation as testing the love that is in his heart, and that love is held by the Master for obedience to God's law.
