Charles Ellicott Commentary Genesis 1:31

"And God saw everything that he had made, and, behold, it was very good. And there was evening and there was morning, the sixth day." — Genesis 1:31 (ASV)

Behold, it was very good. —This final blessing of God’s completed work on the Friday must be compared with the final words of Christ spoken of the second creation, upon the same day of the week, when He said It is finished. Next we must notice that this world was only good until man was placed upon it, but then became very good. This verdict, too, had respect to man as a species, and is not therefore annulled by the fall. In spite, therefore, of the serious responsibilities attendant upon the bestowal of freewill on man, we believe that the world is still for purposes of mercy, and that God not only rejoiced at first, but shall rejoice in His works (Psalms 104:31). (Compare to Psalm 85:10, Romans 5:15, and other similar passages.)
