This frost of law and terrors only tends to harden. Nothing splits the rock or makes the cliff tumble like frost when succeeded by thaw, but frost alone makes the earth like a mass of iron, breaking the ploughshare which would seek to pierce it. A sinner under the influence of the law of God, apart from the gospel, is hardened by despair, and cries, "There is no hope, and therefore after my lusts will I go. Whereas there is no heaven for me after this life, I will make a heaven out of this earth; and since hell awaits me, I will at least enjoy such sweets as sin may afford me here." This is not the fault of the law; the blame lies with the corrupt heart which is hardened by it; yet, nevertheless, such is its effect. When the Lord has wrought by the frost of the law, he sends _the thaw of the gospel_. When the south wind blows from the land of promise, bringing precious remembrances of God's fatherly pity and tender lovingkindness, then straightway the heart begins to soften and a sense of blood-bought pardon speedily dissolves it. The eyes fill with tears, the heart melts in tenderness, rivers of pleasure flow freely, and buds of hope open in the cheerful air. A heavenly spring whispers to the flowers that were sleeping in the cold earth; they hear its voice, and lift up their heads, for "the rain is over and gone; the flowers appear on the earth, the time of the singing of birds is come, and the voice of the turtle is heard in our land." God sendeth his Word, saying, "Thy warfare is accomplished, and thy sin is pardoned;" and when that blessedly cheering word comes with power to the soul, and the sweet breath of the Holy Spirit acts like the warm south wind upon the heart, then the waters flow, and the mind is filled with holy joy, and light, and liberty. "The legal wintry state is gone, The frosts are fled, the spring comes on, The sacred turtle-dove we hear Proclaim the new, the joyful year." Having shown you that there is a parallel between frost and thaw in nature and law and gospel in grace, I would utter the same thoughts concerning grace which I gave you concerning nature.
