=============================
the BIG picture was, that God was teaching us how to HEAR HIM!!!,
and the way He did this was to tell us what we could EAT or not EAT!!!
we learned the art of survival through obeying Him:
we ate many wild mushrooms-berries-greens-fish-turtle-clams, etc. -
but, the true 'lesson' for us was learning HOW to LISTEN to our Lord's Voice',
for there are many 'harmful-poisonous species out there, and so, what our
Lord had us do when we were foraging, was to put our 'hands upon the plants, etc,
and ASK HIM, can we partake??? - and the answer would always be, a 'yes or a no'.
and thus He taught us both what it means to be obedient and to truly HEAR His Voice...
a very good seven year lesson...
