How do we know Christ's eternal kingship is true?

The truth of Christ's eternal kingship is affirmed through numerous biblical texts. Psalm 2 highlights the decree of God declaring Christ as His Son, appointed to reign. This kingship isn't just a title; it is affirmed in the covenant made between God and Christ from eternity. The scriptures affirm that Christ is not only David's son but also his Lord, demonstrating His divine authority. This assurance is crucial; our faith rests on the confidence that Christ's kingship is sovereign and unchanging, established by God's eternal decree.
