Here is, I. Noah's thankful acknowledgment of God's favour to him, in completing the mercy of his deliverance, Gen 8:20. 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, Gen 7:2, Gen 7:3. 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 6:16. 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, Gen 8:21. 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 5:2. 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 (Gen 6:6), 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, Deu 32:36. 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 (Gen 3:17), 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, Gen 6:5. 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 48:8. Thus God remembers that he is flesh, corrupt and sinful, Psa 78:39. 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 (Gen 8:22): "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 33:20, Jer 33:21. We see God's promises to the creatures made good, and thence may infer that his promises to all believers shall be so.

The Lord smelled a sweet savor - That is, he was well pleased with this religious act, performed in obedience to his own appointment, and in faith of the promised Savior. That this sacrifice prefigured that which was offered by our blessed Redeemer in behalf of the world, is sufficiently evident from the words of St. Paul, Eph 5:2 : Christ hath loved us, and given himself for its an offering and a sacrifice to God for a Sweet-Smelling Savor; where the words οσμην ευωδιας of the apostle are the very words used by the Septuagint in this place.

I will not again curse the ground - לא אסף lo osiph, I will not add to curse the ground - there shall not be another deluge to destroy the whole earth: for the imagination of man's heart, כי ki, Although the imagination of man's heart should be evil, i.e. should they become afterwards as evil as they have been before, I will not destroy the earth by a Flood. God has other means of destruction; and the next time he visits by a general judgment, Fire is to be the agent. Pe2 3:7.

While the earth remaineth,.... Which as to its substance may remain for ever, Ecc 1:4 yet as to its form and quality will be changed; that and all in it will be burnt up; there will be an end of all things in it, for so the words are in the original, "as yet all the days of the earth", or "while all the days of the earth" are (i); which shows that there is a time fixed for its continuance, and that this time is but short, being measured by days: but however, as long as it does continue:

seedtime and harvest, and cold and heat, and summer and winter, and day and night, shall not cease; as they had done, or seemed to do during the flood; for the year past there had been no seedtime nor harvest, and it must have been for the most part damp and cold, through the rains, and the abundance of water on earth, that the difference of seasons was not very discernible; as neither of days and nights at some times, especially when the clouds were so black and thick over the heavens, that neither sun, moon, or stars could be seen; and such floods of water continually pouring down, that it must be difficult to know when it was day, and when night; but for the future it is promised, that these should not cease as long as the world stands: "seedtime and harvest"; the time of sowing seed in the earth, and the time of gathering in the fruits of it when ripe, so necessary for the sustenance of man and beast: once in seven years, and once in fifty years indeed, these ceased in the land of Judea, while the people of Israel resided there; but then this was not general all the world over, in other places there were seedtime and harvest: "and cold and heat, and summer and winter"; in some places indeed there is but little cold, in others but little heat, and the difference of summer and winter is not so discernible in some places as in others, yet there is of all these in the world in general. According to Jarchi, "cold" signifies a more severe season than "winter", or the severer part of the winter; and "heat" a hotter season than the summer, or the hotter part of it. The Jews observe, that the seasons of the year are divided into six parts, and two months are to be allowed to each part; which Lyra, from them, and chiefly from Jarchi, thus gives,"to seedtime the last half of September, all October, and half November; to cold, the other half of November, all December, and half January; to winter, half January, all February, and half March: to harvest, half March, all April, and half May; to summer, half May, all June, and half July; to heat, half July, all August, and the first half of September.''But these accounts refer to the land of Judea only: it is enough for the fulfilment of the promise, that they are more or less, at one time of the year or another, in all parts of the world, and so will be until the world shall be no more; and may, in a mystic sense, denote the continuance of the church of God in the world, as long as it endures, and its various vicissitudes and revolutions; sometimes it is a time of sowing the precious seed of the Word; and sometimes it is an harvest, is an ingathering of souls into it; sometimes it is a winter season with it, and all things seem withered and dead; and at other times it is summer, and all things look smiling and cheerful; sometimes it is in a state of coldness and indifference, and at other times exposed to the heat of persecution, and more warm and zealous usually then; sometimes it is night with it, and sometimes day, and so it is like to be, until that state takes place described in Rev 7:16.

Next: Genesis Chapter 9

And the Lord smelled a sweet savour--The sacrifice offered by a righteous man like Noah in faith was acceptable as the most fragrant incense.

Lord said in his heart--same as "I have sworn that the waters of Noah should no more go over the earth" (Isa 54:9).

for--that is, "though the imagination is evil"; instead of inflicting another destructive flood, I shall spare them--to enjoy the blessings of grace, through a Saviour.
