Yeah, I love that song!

I've been looking everywhere for it and can't find anything on it! It goes like this...
Ruler of my heart, You are the Keeper of my soul(x2)
Oh lord, your name is mighty, high above every name.
Your love endures forever!
I heard this at church camp last summer and absolutely loved it, and I want to play it on my guitar, but I can't find any chords anywhere! Anybody have any ideas??
