Lift Up Your Heads

I have long struggled with what Psalm 24 is talking about. "Lift up your heads, oh you gates, and be lifted up, you everlasting doors, that the King of glory may come in. I noticed this week that the next psalm opens with "To You, O Lord, I lift up my soul." And then, in Psalm 27, we pray, "Now my head shall be lifted up above my enemies all around me; I will sing, yes, I will sing praises to the Lord." I wonder if that means anything.
