the sovereignty of God.

"Learn then this basic truth, that the Creator is absolute Sovereign, executing His own will, performing His own pleasure, and considering naught but His own glory. “The Lord hath made all things FOR HIMSELF. (Prov 16:4). And had He not a perfect right to do so? Since God is God, who dare challenge His prerogative? To murmur against Him is rank rebellion. To question His ways is to impugn His wisdom. To criticize Him is sin of the deepest dye. Have we forgotten who He is?"
