On the surface, Psalm 24 describes David and his men as they approached the gates of Jerusalem with the ark of the covenant. And yet, in a much deeper sense, this is a prophetic description of the majestic scene of heaven directly after the ascension of Jesus. For the first time in history, a man actually approached the gates of heaven and demanded that the angelic beings, who guard them with swords of fire, open up those ancient doors for the very first time. Who is this King of glory? He is the God-man, Christ Jesus.
