It is a promise of God, though my friend ...... If God allowed those that are His to fall in a situation as described, He would provide .... supernaturally if need be ..... I think of the children of Israel, where God provided manna in the wilderness,,,,,,
Don't want to turn this into a faith/religious argument at all Preach, but Faith, without works, is fruitless . (as is works without faith.) God had to show the children of Israel what to do and when to do it, and yet they still wandered around in the wilderness for 40 yrs., and some never inherited the promise. Just like God tried to teach them, I feel that I must teach my own. (And if they don't learn...well?) Faith is a great "part" of it, but it takes a willingness to work, to get the job done.
