1. This is as firm as the covenant of providence. It is as the waters of Noah, that is, as that promise which was made concerning the deluge that there should never be the like again to disturb the course of summer and winter, seed-time and harvest, v. 9. God then contended with the world in great wrath, and for a full year, and yet at length returned in mercy, everlasting mercy; for he gave his word, which was as inviolable as his oath, that Noah's flood should never return, that he would never drown the world again; see Gen. viii. 21, 22; ix. 11. And God has ever since kept his word, though the world has been very provoking; and he will keep it to the end; for the world that now is is reserved unto fire. And thus inviolable is the covenant of grace: I have sworn that I would not be wroth with thee, as I have been, and rebuke thee, as I have done. He will not be so angry with them as to cast them off and break his covenant with them (Ps. lxxxix. 34), nor rebuke them as he has rebuked the heathen, to destroy them, and put out their name for ever and ever, Ps. ix. 5.
