Sharon,
It is, most likely, all of the things you mentioned. The greatest effert is
not on our behalf but what Christ has already done, and provided, for us as
His children. The more complex and thelogical we make our walk with Him,
the less we are going to hear His voice and to know and understand His ways.
It is always simple. If it is complex, when it comes to walking with Him,
it isn't God.
Phil.
