The assertion of God's absolute sovereignty in creation, providence, and salvation is basic to biblical belief and biblical praise. The vision of God reigning from His throne is recurrent (1 Kin. 22:19; Is. 6:1; Ezek. 1:26; Dan. 7:9; Rev. 4:2; cf. Ps. 11:4; 45:6; 47:8, 9; Heb. 12:2; Rev. 3:21). We are constantly told in explicit terms that the Lord (Yahweh) reigns as king, exercising dominion over great and small alike (Ex. 15:18; Ps. 47; 93; 96:10; 97; 99:1-5; 146:10; Prov. 16:33; 21:1; Is. 24:23; 52:7; Dan. 4:34, 35; 5:21-28; 6:26; Matt. 10:29-31). God's dominion is total: He wills as He chooses, and carries out all that He wills, and none can stay His hand, or thwart His plans. He exercises His rule in the normal course of life, as well as in more remarkable interventions or miracles.
God's rational creatures, angelic and human, have free agency, that is, the power of personal decision as to what they will do. We would not be moral beings, answerable to God the Judge, if it were not so. Nor would it be possible to distinguish, as Scripture does, between the bad purposes of human agents and the good purposes of God, who sovereignly overrules human action as a planned means to His own goals (Gen. 50:20; Acts 2:23; 13:26-39). Yet the fact of free agency confronts us with mystery. God's control over our free actions, actions chosen by ourselves, is as complete as it is over anything else; but how this can be we do not know. Despite this control, God is not, and cannot be, the author of sin. God has conferred responsibility on moral agents for their thoughts, words, and deeds, according to His justice.
Ps. 93 teaches that God's sovereign rule (a) guarantees the stability of the world against all the forces of chaos (vv. 1-4), (b) confirms the trustworthiness of all God's utterances and directives (v. 5), and (c) calls for the worship of His people (v. 5). The whole psalm expresses joy, hope, and confidence in the Almighty.See more on the will of God here.
