How do we know the doctrine of Christ's reign is true?

Scripture assures us of Christ's reign, particularly through passages like Revelation 20, which depicts His binding of Satan. This doctrine emphasizes Jesus's complete sovereignty and His ongoing rule over the church throughout the dispensation of grace. Importantly, His resurrection and ascension underscore His authority, fulfilling God's promise to save His people and ensuring that the gospel goes forth triumphantly. The assurance of Christ's reign is thus woven throughout Scripture as evidence of His unyielding purpose and plan for redemption.
