How do we know Jesus is King of glory?

Jesus is referred to as the King of glory primarily due to His dual nature as both God and man, affirmed through passages such as Philippians 2:9 and Hebrews 1:3. His glory is evident not only in His divine attributes but also in His redemptive work, where He, as a human, endured suffering and death, ultimately receiving a name above every name after His resurrection. His ascension into heaven, as described in the Psalms, serves to validate His title and authority, as He now reigns in majesty at the right hand of God, interceding for His people.
