Do you trust us to guide you? 
Most likely you do.  The bigger
question is, do you trust yourself to hear accurately and to trust that it is
not your own voice that you hear?  There
is only one way of earning that trust. 
You take the step off the cliff. 
There is no danger in doing so, for of course we do not speak
literally.  Your true guides would never
tell you to step off of a cliff if it would cause you harm.  That is one way in which to discern
Truth.  Higher guidance is always loving,
always helpful.  You are always better
off for having heeded it.  With that kind
of advice, what difference does it make if the loving advice comes from your
guides, your higher self, or your imagination? 
It is all the same Consciousness. 
Heed it well.
