3. The next thought concerning the Lord's work in nature was the _variety_ of it. Frost produces a sort of trinity in unity--snow, hoarfrost, ice; and when the thaw comes its ways are many. So it is with God in the heart. Conviction comes not alike to all. Some convictions fall as the snow from heaven: you never hear the flakes descend, they alight so gently one upon the other. There are soft-coming convictions; they are felt, but we can scarcely tell when we began to feel them. A true work of repentance may be of the gentlest kind. On the other hand, the Lord casteth forth his ice like morsels, the hailstones rattle against the window, and you think they will surely force their way into the room, and so to many persons convictions come beating down till they remind you of hailstones. There is variety. It is as true a frost which produces the noiseless snow as that which brings forth the terrible hail. Why should you want hailstones of terror? Be thankful that God has visited you, but do not dictate to him the way of his working. With regard to the gospel thaw. If you may but be pardoned by Jesus, do not stipulate as to the manner of his grace. Thaw is universal and gradual, but its commencement is not always discernible. The chains of winter are unloosed by degrees: the surface ice and snow melt, and by and by the warmth permeates the entire mass till every rock of ice gives way. But while thaw is universal and visible in its effects you cannot see the mighty power which is doing all this. Even so you must not expect to discern the Spirit of God. You will find him gradually operating upon the entire man, enlightening the understanding, freeing the will, delivering the heart from fear, inspiring hope, waking up the whole spirit, gradually and universally working upon the mind and producing the manifest effects of comfort, and hope, and peace; but you can no more see the Spirit of God than you can see the south wind. The effect of his power is to be felt, and when you feel it, do not marvel if it be somewhat different from what others have experienced. After all, there is a singular likeness in snow and hoarfrost and ice, and so there is a remarkable sameness in the experience of all God's children; but still there is a great variety in the inward operations of divine grace.
