He “worketh all things after the counsel of His own will” (Eph 1:11).
God was under no constraint, no obligation, no necessity to create. That He chose to do so was purely a sovereign act on His part, caused by nothing outside Himself, determined by nothing but His own mere good pleasure; for He “worketh all things after the counsel of His own will” (Eph 1:11). That He did create was simply for His manifestative glory. God so pleased He might have continued alone for all eternity, without making known His glory unto creatures. Whether He should do so or not was determined solely by His own will. He was perfectly blessed in Himself before the first creature was called into being. How vastly different is the God of Scripture from the “god” of the average pulpit!
He is solitary in His majesty, unique in His excellency, peerless in His perfections. He sustains all, but is Himself independent of all. He gives to all, but is enriched by none.
