This is a great question. Over the years of playing Gospel music, primarly as a lead guitarist, I have learned a few things. First, a series of well placed soulful notes is more important than a fast riff. Second, milk your notes through slowly bending the strings and then, when you land back on your note, vibrate your fingers against the fret board. Do not be in a hurry. Third, if you want to jam out, play fast and funky with the least amount of effects. I tend to use reverb with just enough gain to begin to break up the sound. In some Gospel songs, a screaming lead with lots of distortion is cool, but any up tempo, more traditional song does not need much effect to be powerful. Just some ideas I have found helpful.....
