John Hannah, To God be the Glory, Crossway, 2000, p. 16.
God’s chief end in the creation could not have been the creation itself, because the world would then have to have been eternal and equal with God. Since the world is not eternal but an effect caused by the power of God, it could not be the ultimate end of itself. This would lift an effect into the realm of pure cause; a cause that we know is God alone. It would be making a secondary cause into a final cause.
