I had been hoping to possibly figure out a couple other seeds that I'd been unsuccessfully chipping away at, but then Psalm 46 came up in another context, which got me back to a setting of it that I had started a while ago. I had put it away since it felt too derivative at the time, but I decided to go with that direction and then even attempted to write a chorus that was "Hillsong"-ish (which is not my go-to style).
The Psalm has a refrain that happens a couple times:
The LORD of hosts is with us;
the God of Jacob is our fortress.
And it also points to the new Jerusalem in Revelation 22.
Demo here.
