Who wouldst not fear Thee, O Lord God of Hosts, most high and most terrible? For Thou art Lord alone. Thou hast made heaven and the heaven of heavens, the earth and all things that are therein, and in Thy hand is the soul of every living thing. Thou sittest king upon the flood; yea, Thou sittest king forever. Thou art a great king over all the earth. Thou art clothed with strength; honor and majesty are before Thee. Amen.
God’s sovereignty is the attribute by which He rules His entire creation, and to be sovereign God must be all-knowing, all-powerful, and absolutely free. The reasons are these:
Were there even one datum of knowledge, however small, unknown to God, His rule would break down at that point. To be Lord over all the creation, He must possess all knowledge. And were God lacking one infinitesimal modicum of power, that lack would end His reign and undo His kingdom; that one stray atom of power would belong to someone else and God would be a limited ruler and hence not sovereign.
Furthermore, His sovereignty requires that He be absolutely free, which means simply that He must be free to do whatever He wills to do anywhere at any time to carry out His eternal purpose in every single detail without interference. Were He less than free He must be less than sovereign.
Gird your sword upon your side, / O mighty one; / clothe yourself with splendor and majesty. Psalm 45:3
Were there even one datum of knowledge, however small, unknown to God, His rule would break down at that point. To be Lord over all the creation, He must possess all knowledge.
Sovereign Lord, You are King over all that exists. Who could not fear You?
