Please help me identify this song!

**UPDATE:  Thanks to Jason in the comments of this post, as well as @graceslick91 on Twitter for helping me figure it out.  The song is called “Surrender Susan” by Jon Abel.**

I have a very large music library, and recently, while listening to some music, a song came on.  This song has been in my head for a few weeks now, and I cannot remember for the life of me who sings it or what it is called.

I have searched Google up and down for the words I remember, and nothing comes up.

Here is what I remember:

1.  It’s a mostly acoustic song.  Acoustic guitar, drums, bass, not much more than that.
2.  It is a man singing
3.  Here are the lyrics I remember (or, something similar to them):
4.  I *think* it is on fairly new cd.  Maybe it came out over the last few years?

verse:  “Do I really love her enough to let her go?”

chorus:  “What it all comes down to is this / she was never really mine, but always His”

Anyone have some ideas?!
