For what should I be repentant?
Herein in the blessing of the repentant sinner:
''Blithe is he whose rebellion is lifted, whose sin is covered.
Blithe is the humanity unto whom Yah Veh fabricateth not perversity, and in whose spirit there is no deceit''.
If you can't fathom why you need the grace of repentance it is a sure sign you are in need of it.
