3. Notice in the next place the _variety_ of the Divine operations in nature. When the Lord is at work with frost as his tool he creates snow, a wonderful production, every crystal being a marvel of art; but then he is not content with snow--from the same water he makes another form of beauty which we call hoarfrost, and yet a third lustrous sparkling substance, namely glittering ice; and all these by the one agency of cold. What a marvellous variety the educated eye can detect in the several forms of frozen water! The same God who solidified the flood with cold soon melts it with warmth; but even in thaw there is no monotony of manner: at one time the joyous streams rush with such impetuosity from their imprisonment that rivers are swollen and floods cover the plain; at another time by slow degrees, in scanty driblets, the drops regain their freedom. The same variety is seen in every department of nature. So in providence the Lord has a thousand forms of frosty trials with which to try his people, and he has ten thousand beams of mercy with which to cheer and comfort them. He can afflict you with the snow trial, or with the hoarfrost trial, or with the ice trial, if he will; and anon he can with his word relax the bonds of adversity, and that in countless ways. Whereas men are tied to two or three methods in accomplishing their will, God is infinite in understanding and worketh as he wills by ways unguessed of mortal mind. 4. I shall ask you also to consider the works of God in nature in their _swiftness_. It was thought a wonderful thing in the days of Ahasuerus that letters were sent by post upon swift dromedaries. In our country we thought we had arrived at the age of miracles when the axles of our cars glowed with speed, and now that the telegraph is at work we stretch out our hands into infinity; but what is our rapidity compared with that of God's operations? Well does the text say, "He sendeth forth his commandment upon earth: his word runneth very swiftly." Forth went the word, "Open the treasures of snow," and the flakes descended in innumerable multitudes; and then it was said, "Let them be closed," and not another snow-feather was seen. Then spake the Master, "Let the south wind blow and the snow be melted": lo, it disappeared at the voice of his word. Believer, you cannot tell how soon God may come to your help. "He rode upon a cherub and did fly," says David; "yea, he did fly upon the wings of the wind." He will come from above to rescue his beloved. He will rend the heavens and come down; with such speed will he descend, that he will not stay to draw the curtains of heaven, but he will rend them in his haste, and make the mountains to flow down at his feet, that he may deliver those who cry unto him in the hour of trouble. That mighty God who can melt the ice so speedily can take to himself the same eagle wings, and haste to your deliverance. Arise, O God! and let thy children be helped, and that right early.
