God very frequently acts in grace in such a manner that we can find a parallel in nature. For instance, God says, “… as the rain cometh down and the snow from heaven, and returneth not thither, … so shall my word be, …it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.” We find him speaking concerning the coming of Christ, “He shall come down like rain upon the mown grass: as showers that water the earth.” We find him likening the covenant of grace to the covenant which he made with Noah concerning the seasons, and with man concerning the different revolutions of the year—“Seed-time and harvest, and cold and heat, and summer and winter, and day and night shall not cease.” We find that the works of creation are very frequently the mirror of the works of grace, and that we can draw figures from the world of nature to illustrate the great acts of God in the world of his grace towards his people. But sometimes God oversteps nature. In nature after evening comes night. The sun has had its hours of journeying; the fiery steeds are weary; they must rest. Lo, they descend the azure steeps and plunge their burning fetlocks in the western sea, while night in her dark chariot follows at their heels. God, however, oversteps the rule of nature. He is pleased to send to his people times when the eye of reason expects to see no more day, but fears that the glorious landscape of God’s mercies will be shrouded in the darkness of his forgetfulness. But instead, God overleaps nature, and declares that at evening time, instead of darkness there shall be light.
For meditation: The text has only ever been true on one occasion in a physical sense (Joshua 10:12-14), but God, to whom even the darkness is light (Psalm 139:12), is always repeating the event spiritually in the lives of his people.
