III. THE CERTAINTIES OF DIVINE GRACE. "They shall be as white as snow." Where sin abounds, grace shall more abound. In God there is mercy to pardon every sin,[3] and grace to cleanse from every form and degree of moral pollution. Here, then, we have--+1. A reason for repentance.+ There is no argument so powerful as this: God is ready to forgive. Many a prodigal has been deterred from saying, "I will arise and go to my father," by a remembrance of his father's sternness, and by a doubt as to whether his father would receive him. But no such doubt need deter _us._ We are not called to the exercises of a sorrow that will be unavailing. Our Father waits to be gracious.[4] Hear His solemn and touching message (ch. lv. 6, 7; TEXT). +2. An encouragement for those who are striving after moral purity.+ Many who try to live a Christian life grow discouraged. There are discouragements that come from _without:_ the unfavourable spiritual atmosphere in which they live, the glaring inconsistencies of some of the professing Christians by whom they are surrounded, the low tone of the spiritual life of those whose conduct is not so open to censure. Still sorer discouragements come from _within:_ the faults that will not be shaken off; the evil tendencies that will manifest themselves; the evil thoughts that will keep welling up from the fountain of the heart, revealing its intense depravity. These things are carefully hidden from men, but God knows them, and the believer knows them, and because of them is apt to grow discouraged. It seems to him that he can never be "made meet for the inheritance of the saints in light." But God has declared that he shall be: God has undertaken to perfect him in purity. "Be of good courage, all ye that hope in the Lord." God is able to make all grace abound toward you, and He is faithful to all His promises. See what He has promised in our text. He has already fulfilled this promise in innumerable cases (Rev. vii. 9), and He will fulfil it in yours. Be not discouraged because your moral progress is so slow. How long does the sun shine on the fruit seemingly in vain! All the summer the peach remains hard as a stone. But the sun is _not_ shining in vain. Some week in the autumn this is seen. All at once it softens and becomes ripe; not as a result of that one week's sun, but of all the sunlight and warmth of the preceding weeks. The chestnut opens in a night; but for months the opening process is going on. In a moment many chemicals seem to crystallise, but the process of crystallisation goes on long before it becomes apparent. So there is a ripening, a crystallising, a cleansing process going on in the heart of the believer: though we see it not now, yet we shall have ample proof of it by and by. In this matter walk by faith, not by sight. Be of good courage! We shall yet be "white as snow." FOOTNOTES:
