One question went through my mind as I watched this video clip..."What was God's reaction?" I know the unsuspecting people in the food court had to be pleasantly surprised with such a performance, and I'm sure they were blessed. But I couldn't help imagine the living creatures in heaven (Rev. 4:8) peering down to see who was joining them with a song of praise, as they sang day and night around the throne of the King of Kings and Lord of Lords. Heaven and earth praising the One whose kingdom will never end, the One who will reign forever and ever - Hallelujah!
It's not hard to imagine how it pleased God, and that He smiled.
And every creature which is in heaven and on the earth and under the earth and such as are in the sea,
and all that are in them, I heard saying:
"Blessing and honor and glory and power
Be to Him who sits on the throne,
And to the Lamb, forever and ever!"
