John Hannah, To God be the Glory, Crossway, 2000, p. 17.
It is illogical to think that an all-sufficient God created the world because of some personal need or internal inadequacy. There is no inadequacy in God. God is perfect in all His being and in all His ways. He is infinitely glorious and unchangeably happy. He has no need of improvement. God could not better His own perfection or see a need to. It would mean that God was not perfect before He did so.
