Watch the Higher Ground - 3 online guitar lesson by Richard Kiser from Gospel Fingerstyle Guitar
The intro is a fairly simple, on the 4th string slide the note from the 4th to the 5th fret and play it along with open third and second strings in succession, then the 3rd fret 4th string, then the 2nd fret the same way, and next open, (all on the forth string). before you play the first bar of the melody of the first verse. Once again the intro helps to set the overall tempo of the song. This one sounds better if it is not played too fast so don't rush it.
