“I have a song called ‘Savior’s Shadow’ on my current album that I actually dreamed,” Blake shared in a video from the set of The Voice. “I woke up and there was more of the song in my dream, but all I could remember was the first verse—I sang it into my phone and I never forgot it.”

“I’m standing in my Savior’s shadow / He is watching over me / I feel the rain, I hear the thunder / As he cries for me,” Blake sings in the first verse.

After Blake wrote a second verse for the song, he called on songwriters Jessi Alexander and Jon Randall to help finish the tune.

“I would walk around the next couple of months singing that verse, not really knowing what it meant,” Blake adds. “Eventually, I wrote another verse to the song. I realized I was onto something that was special to me. I called my friends Jessi Alexander and Jon Randall to help me with this thing and they did. It turned out to be one of my favorite songs that I’ve ever been a part of as a writer. If you get a chance to listen to it, you’ll understand why.”

You can catch more of Blake as he coaches his way through The Voice every Monday and Tuesday night at 7 p.m. CT on NBC.
