If you’ve never heard the Casting Crowns version of this song, you need to listen. This is nothing like the traditional song, and it is incredibly moving.
Christmas Bells, the original poem – yes, poem, in case you didn’t know – was written by Henry Wadsworth Longfellow. You can read it here.
He will not allow your foot to be moved.
He who keeps you will not slumber.
Behold, he who keeps Israel
will neither slumber nor sleep.
Psalms 121:3-4 WEB
