Regina Spektor's Song - "The Call" from Narnia's Prince Caspian
This isn't really a "Christian" song (that I know of), but it sure is beautiful:
It's from the Narnia movie, Prince Caspian. And for some reason, it reminds me of Jesus's promise to come back again, a hope I cling to in these dark times.
(I've been addicted to C.S. Lewis lately, ever since lockdown started last year. And not even just his writings but the biographies people have written about him. I'm on my 7th Lewis biography so far. And I've got a couple more to read. I just can't get enough. Addicted, I tell you. Addicted.)
