"There can be little doubt that this psalm was in the mind of John as he wrote Revelation 19:6-21. As he looked forward to the marriage of Christ, the Lamb, in heaven, he recalled how the bride clothed herself with acts of righteousness in preparation for Him ( Revelation 19:6-8). Then John described the royal groom going forth to battle in righteousness ( Revelation 19:11-21). Psalm 45 , then, is typological of the greater Davidic King, Jesus Christ." [1][source]

We who are believers should rejoice in our glorious King who will one day experience full union with His bride, the church ( Ephesians 5:23-32). He is worthy of our praise because He is completely true, humble, and righteous. We should also submit to His authority in view of who He is. We can look forward with great anticipation to our union with Him and our glorious future with Him from then on. His kingdom will endure forever, and everyone will honor His name throughout eternity.
