How do we know Jesus Christ is truly sovereign?

The sovereignty of Christ is substantiated throughout both the Old and New Testaments. Texts such as Isaiah 54:5 and Proverbs 21:1 illustrate God's control over creation and human affairs. In 1 Timothy 6:16, we learn that God alone possesses immortality, and that implies an eternal authority. Furthermore, the resurrection of Christ is the ultimate demonstration of His sovereignty over death. Thus, believers can confidently affirm Christ's sovereign rule based on God’s unshakeable declarations in His Word.
