Here are some preaching Chording in Ab I like to use
Ab/ Gb Bb C F/ D Eb AB
Ab/ Ab Eb /C F Bb
C/ Gb Bb/ C F Bb
Db/ F B/ B Eb F Bb
D/ F B/ F Ab B D
Ab/ Ab Eb/Gb Db Eb F Ab
Ab/Ab Eb/Gb C F Ab
Throw in the blues scale and you are all set, of course this is only according to how the preacher is closing, this doesn't really work to well with the old school baptist closers, but I will post those kind of chords later.
Hope this Helps anyone
God bless
