Short song: "Wake up, O sleeper"

A couple weeks ago I came across the following passage in Ephesians 5:14:

Wake up, O sleeper,
rise from the dead,
and Christ will shine on you.

The message continues to stir me. Apparently these could have been the lyrics to a hymn sung by early Christians. I've written a short song based on the words.
