20 And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.   21 And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done.   22 While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.

      Here is, I. Noah's thankful acknowledgment of God's favour to him, in completing the mercy of his deliverance, v. 20. 1. He built an altar. Hitherto he had done nothing without particular instructions and commands from God. He had a particular call into the ark, and another out of it; but, altars and sacrifices being already of divine institution for religious worship, he did not stay for a particular command thus to express his thankfulness. Those that have received mercy from God should be forward in returning thanks, and do it not of constraint, but willingly. God is pleased with free-will offerings, and praises that wait for him. Noah was now turned out into a cold and desolate world, where, one would have thought, his first care would have been to build a house for himself; but, behold, he begins with an altar for God: God, that is the first, must be first served; and he begins well that begins with God. 2. He offered a sacrifice upon his altar, of every clean beast, and of every clean fowl--one, the odd seventh that we read of, ch. vii. 2, 3. Here observe, (1.) He offered only those that were clean; for it is not enough that we sacrifice, but we must sacrifice that which God appoints, according to the law of sacrifice, and not a corrupt thing. (2.) Though his stock of cattle was so small, and that rescued from ruin at so great an expense of care and pains, yet he did not grudge to give God his dues out of it. He might have said, "Have I but seven sheep to begin the world with, and must one of these seven be killed and burnt for sacrifice? Were it not better to defer it till we have greater plenty?" No, to prove the sincerity of his love and gratitude, he cheerfully gives the seventh to his God, as an acknowledgment that all was his, and owing to him. Serving God with our little is the way to make it more; and we must never think that wasted with which God is honoured. (3.) See here the antiquity of religion: the first thing we find done in the new world was an act of worship, Jer. vi. 16. We are now to express our thankfulness, not by burnt-offerings, but by the sacrifices of praise and the sacrifices of righteousness, by pious devotions and a pious conversation.

      II. God's gracious acceptance of Noah's thankfulness. It was a settled rule in the patriarchal age: If thou doest well, shalt thou not be accepted? Noah was so. For,

      1. God was well pleased with the performance, v. 21. He smelt a sweet savour, or, as it is in the Hebrew, a savour of rest, from it. As, when he had made the world at first on the seventh day, he rested and was refreshed, so, now that he had new-made it, in the sacrifice of the seventh he rested. He was well pleased with Noah's pious zeal, and these hopeful beginnings of the new world, as men are with fragrant and agreeable smells; though his offering was small, it was according to his ability, and God accepted it. Having caused his anger to rest upon the world of sinners, he here caused his love to rest upon this little remnant of believers.

      2. Hereupon, he took up a resolution never to drown the world again. Herein he had an eye, not so much to Noah's sacrifice as to Christ's sacrifice of himself, which was typified and represented by it, and which was indeed an offering of a sweet-smelling savour, Eph. v. 2. Good security is here given, and that which may be relied upon,

      (1.) That this judgment should never be repeated. Noah might think, "To what purpose should the world be repaired, when, in all probability, for the wickedness of it, it will quickly be in like manner ruined again?" "No," says God, "it never shall." It was said (ch. vi. 6), It repented the Lord that he had made man; now here he speaks as if it repented him that he had destroyed man: neither means a change of his mind, but both a change of his way. It repented him concerning his servants, Deut. xxxii. 36. Two ways this resolve is expressed:-- [1.] I will not again curse the ground, Heb. I will not add to curse the ground any more. God had cursed the ground upon the first entrance of sin (ch. iii. 17), when he drowned it he added to that curse; but now he determines not to add to it any more. [2.] Neither will I again smite any more every living thing; that is, it was determined that whatever ruin God might bring upon particular persons, or families, or countries, he would never again destroy the whole world till the day shall come when time shall be no more. But the reason of this resolve is very surprising, for it seems the same in effect with the reason given for the destruction of the world: Because the imagination of man's heart is evil from his youth, ch. vi. 5. But there is this difference--there it is said, The imagination of man's heart is evil continually, that is, "his actual transgressions continually cry against him;" here it is said, It is evil from his youth or childhood. It is bred in the bone; he brought it into the world with him; he was shapen and conceived in it. Now, one would think it should follow, "Therefore that guilty race shall be wholly extinguished, and I will make a full end." No, "Therefore I will no more take this severe method; for," First, "He is rather to be pitied, for it is all the effect of sin dwelling in him; and it is but what might be expected from such a degenerate race: he is called a transgressor from the womb, and therefore it is not strange that he deals so very treacherously," Isa. xlviii. 8. Thus God remembers that he is flesh, corrupt and sinful, Ps. lxxviii. 39. Secondly, "He will be utterly ruined; for, if he be dealt with according to his deserts, one flood must succeed another till all be destroyed." See here, 1. That outward judgments, though they may terrify and restrain men, yet cannot of themselves sanctify and renew them; the grace of God must work with those judgments. Man's nature was as sinful after the deluge as it had been before. 2. That God's goodness takes occasion from man's sinfulness to magnify itself the more; his reasons of mercy are all drawn from himself, not from any thing in us.

      (2.) That the course of nature should never be discontinued (v. 22): "While the earth remaineth, and man upon it, there shall be summer and winter (not all winter as had been this last year), day and night," not all night, as probably it was while the rain was descending. Here, [1.] It is plainly intimated that this earth is not to remain always; it, and all the works in it, must shortly be burnt up; and we look for new heavens and a new earth, when all these things must be dissolved. But, [2.] As long as it does remain God's providence will carefully preserve the regular succession of times and seasons, and cause each to know its place. To this we owe it that the world stands, and the wheel of nature keeps it track. See here how changeable the times are and yet how unchangeable. First, The course of nature always changing. As it is with the times, so it is with the events of time, they are subject to vicissitudes--day and night, summer and winter, counterchanged. In heaven and hell it is not so, but on earth God hath set the one over against the other. Secondly, Yet never changed. It is constant in this inconstancy. These seasons have never ceased, nor shall cease, while the sun continued such a steady measurer of time and the moon such a faithful witness in heaven. This is God's covenant of the day and of the night, the stability of which is mentioned for the confirming of our faith in the covenant of grace, which is no less inviolable, Jer. xxxiii. 20, 21. We see God's promises to the creatures made good, and thence may infer that his promises to all believers shall be so.

      8 And God spake unto Noah, and to his sons with him, saying,   9 And I, behold, I establish my covenant with you, and with your seed after you;   10 And with every living creature that is with you, of the fowl, of the cattle, and of every beast of the earth with you; from all that go out of the ark, to every beast of the earth.   11 And I will establish my covenant with you; neither shall all flesh be cut off any more by the waters of a flood; neither shall there any more be a flood to destroy the earth.

      Here is, I. The general establishment of God's covenant with this new world, and the extent of that covenant, v. 9, 10. Here observe, 1. That God is graciously pleased to deal with man in the way of a covenant, wherein God greatly magnifies his condescending favour, and greatly encourages man's duty and obedience, as a reasonable and gainful service. 2. That all God's covenants with man are of his own making: I, behold, I. It is thus expressed both to raise our admiration--"Behold, and wonder, that though God be high yet he has this respect to man," and to confirm our assurances of the validity of the covenant--"Behold and see, I make it; I that am faithful and able to make it good." 3. That God's covenants are established more firmly than the pillars of heaven or the foundations of the earth, and cannot be disannulled. 4. That God's covenants are made with the covenanters and with their seed; the promise is to them and their children. 5. That those may be taken into covenant with God, and receive the benefits of it, who yet are not capable of restipulating, or giving their own consent. For this covenant is made with every living creature, every beast of the earth.

      II. The particular intention of this covenant. It was designed to secure the world from another deluge: There shall not any more be a flood. God had drowned the world once, and still it was as filthy and provoking as ever, and God foresaw the wickedness of it, and yet promised he would never drown it any more; for he deals not with us according to our sins. It is owing to God's goodness and faithfulness, not to any reformation of the world, that it has not often been deluged and that it is not deluged now. As the old world was ruined to be a monument of justice, so this world remains to this day, a monument of mercy, according to the oath of God, that the waters of Noah should no more return to cover the earth, Isa. liv. 9. This promise of God keeps the sea and clouds in their decreed place, and sets them gates and bars; hitherto they shall come, Job xxxviii. 10, 11. If the sea should flow but for a few days, as it does twice every day for a few hours, what desolation would it make! And how destructive would the clouds be, if such showers as we have sometimes seen were continued long! But God, by flowing seas and sweeping rains, shows what he could do in wrath; and yet, by preserving the earth from being deluged between both, shows what he can do in mercy and will do in truth. Let us give him the glory of his mercy in promising and of his truth in performing. This promise does not hinder, 1. But that God may bring other wasting judgments upon mankind; for, though he has here bound himself not to use this arrow any more, yet he has other arrows in his quiver. 2. Nor but that he may destroy particular places and countries by the inundations of the sea or rivers. 3. Nor will the destruction of the world at the last day by fire be any breach of his promise. Sin which drowned the old world will burn this.
