It's been a long time since I have heard this hymn, much less sung it (the tune, by the way, is Truro). I never realized it is an Advent hymn until this year. But the lyrics, based on Psalm 24:7-10, originally written by George Weissel and translated by Catherine Winkworth, fit the themes of preparing and waiting:
1. Lift up your heads, ye mighty gates;
behold, the King of glory waits;
the King of kings is drawing near;
the Savior of the world is here!
2. Fling wide the portals of your heart;
make it a temple, set apart
from earthly use for heaven's employ,
adorned with prayer and love and joy.
3. Redeemer, come, with us abide;
our hearts to thee we open wide;
let us thy inner presence feel;
thy grace and love in us reveal.
4. Thy Holy Spirit lead us on
until our glorious goal is won;
eternal praise, eternal fame
be offered, Savior, to thy name!
