Noah was now gone out into a desolate world, where, one might have thought, his first care would have been to build a house for himself, but he begins with an alter for God. He begins well, that begins with God. Though Noah's stock of cattle was small, and that saved at great care and pains, yet he did not grudge to serve God out of it. Serving God with our little is the way to make it more; we must never think that is wasted with which God is honoured. The first thing done in the new world was an act of worship. We are now to express our thankfulness, not by burnt-offerings, but by praise, and pious devotions and conversation. God was well pleased with what was done. But the burning flesh could no more please God, than the blood of bulls and goats, except as typical of the sacrifice of Christ, and expressing Noah's humble faith and devotedness to God. The flood washed away the race of wicked men, but it did not remove sin from man's nature, who being conceived and born in sin, thinks, devises, and loves wickedness, even from his youth, and that as much since the flood as before. But God graciously declared he never would drown the world again. While the earth remains, and man upon it, there shall be summer and winter. It is plain that this earth is not to remain always. It, and all the works in it, must shortly be burned up; and we look for new heavens and a new earth, when all these things shall be dissolved. But as long as it does remain, God's providence will cause the course of times and seasons to go on, and makes each to know its place. And on this word we depend, that thus it shall be. We see God's promises to the creatures made good, and may infer that his promises to all believers shall be so.
