“God is Sovereign” is just another way to say, “God is God.” My mentor/pastor, Dr. Richard Strauss, had this working definition of sovereignty: “God is highest and best, and does what He pleases in heaven and earth.” God is sovereign, working His will and accomplishing His purposes as He pleases.
One great statement about the sovereignty of God came from the pen of Paul to the Corinthian Christ followers. He wrote that Christ will put “an end to all rule and all authority and power. For He must reign till He has put all enemies under His feet” [1 Corinthians 15.24-25]. Every second of time from Christ’s ascension [Acts 1.11] to His triumphant return [Revelation 19.6-7a] is in this verse.
Christ reigns now. He rules over every sinful action, every evil purpose, every dark deed, and every wicked world leader. There is no person, no President, no dictator, no Prime Minister, no Ayatollah, no movement, no government, that can derail His perfect reign. “He must reign,” Paul said.
And when His reign is finally consummated, it will mean the defeat of every aspect of this sinful world, not the least of which is the last enemy, death [1 Corinthians 15.26]. No part of this sin-cursed world will be left untouched. All will be made new.
That is really good news. From start to finish, from this moment throughout all eternity, God is sovereign.
Our God is in heaven doing whatever He wants to do. Psalm 115.3 [The MESSAGE Paraphrase]
