And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.

Wesley's Notes

1:31 We have here the approbation and conclusion of the whole work of creation. Observe, The review God took of his work, he saw every thing that he had made - So he doth still; all the works of his hands are under his eye; he that made all sees all. The complacency God took in his work. When we come to review our works we find to our shame, that much has been very bad; but when God reviewed his, all was very good.
1. It was good. Good, for it is all agreeable to the mind of the creator. Good, for it answers the end of its creation. Good, for it is serviceable to man, whom God had appointed lord of the visible creation. Good, for it is all for God's glory; there is that in the whole visible creation which is a demonstration of God's being and perfections, and which tends to beget in the soul of man a religious regard to him.
2. It was very good - Of each day's work (except the second) it was said that it was good, but now it is very good. For,
1. Now man was made, who was the chief of the ways of God, the visible image of the Creator's glory,
2. Now All was made, every part was good, but all together very good. The glory and goodness, the beauty and harmony of God's works both of providence and grace, as this of creation, will best appear when they are perfected. The time when this work was concluded. The evening and the morning were the sixth day - So that in six days God made the world. We are not to think but that God could have made the world in an instant: but he did it in six days, that he might shew himself a free agent, doing his own work, both in his own way, and in his own time; that his wisdom, power and goodness, might appear to us, and be meditated upon by us, the more distinctly; and that he might set us an example of working six days, and resting the seventh. And now as God reviewed his work, let us review our meditations upon it; let us stir up ourselves, and all that is within us, to worship him that made the, heaven, earth, and sea, and the fountains of waters. All his works in all places of his dominion bless him, and therefore bless thou the Lord, O my soul.

Matthew Henry's Concise Commentary

1:31 When we come to think about our works, we find, to our shame, that much has been very bad; but when God saw his work, all was very good. Good, for it was all just as the Creator would have it to be. All his works, in all places of his dominion, bless him; and therefore, bless thou the Lord, O my soul. Let us bless God for the gospel of Christ, and when we consider his almighty power, let us sinners flee from the wrath to come. If new-created unto the image of God in holiness, we shall at length enter the new heavens and new earth, wherein dwelleth righteousness.
