It is posts like these that make me so grateful my church loves CCM music where its ALL about the guitar baby.

On the few occasions we do gospel songs, i either sit them out or i play some bluesy licks here and there...in between the vocals of course.
I'd say listen to a lot of gospel CDs and try and analyze what the guitarist is doing. Most times the sound is really hidden but you can kind of pick out what he is doing.
Other than this, i can offer you no help.
