“Lift up your heads, you gates; be lifted up, you ancient doors, that the King of glory may come in. Who is this King of glory? The Lord strong and mighty, the Lord mighty in battle. Lift up your heads, you gates; lift them up, you ancient doors, that the King of glory may come in. Who is he, this King of glory? The Lord Almighty— he is the King of glory.” Psalm 24:7‭-‬10

Another psalm by David, Psalm 24, was structured to be a call and response–the worship leader would call and the participants would respond. The Psalm’s first paragraph, for example, would go like this:
LEADER: “The earth is the Lord ʼs, and everything in it, the world, and all who live in it;”
PARTICIPANTS: “for He founded it on the seas and established it on the waters.”

So it would naturally follow that verses 7-10 would go like this:
LEADER: “Lift up your heads, you gates; be lifted up, you ancient doors, that the King of glory may come in.”
PARTICIPANT: “Who is this King of glory?”
LEADER: “The Lord strong and mighty, the Lord mighty in battle”.

However, what does this mean-how can a gate, lift up its head?
This could have a couple of meanings. One, it means, “wake up”! A sleeping person in a sitting position, will raise their head upon being awakened. Two, it could means, open up! After all that’s necessary to be a good gate and for Someone, in this case, the “King of glory”, to come in!

The emphasis, however, of the passage is on the King of Glory, not the gate!
The King of Glory is Jesus, “The Lord strong and mighty, the Lord mighty in battle”–for us, the Lord, Who fights our battles!

In verse 10, He’s the Lord, Almighty.

In contemporary terms, we are the gates and Jesus is still the King!

What is necessary for Him to come in? We must wake up and open up our lives to Him. This applies to belivers and non-believers alike!

Wake up! Open up! Listen up! Jesus, the King of Glory, the One Who fights for us, the Lord Almighty wants to come in!

Think about it!
