Yes, it's true. We must have air, water and food in order to survive. Now, my 98 year old mother needs my support so I am dedicated to getting whatever she needs. Mama and I have discussed this very situation. What can we do when the food and water is taken away from us? Christ said it best when He was dying on the cross:
“‘they will say to the mountains, “Fall on us!”
and to the hills, “Cover us!”
I Peter 12:
"In all this you greatly rejoice, though now for a little while you may have had to suffer grief in all kinds of trials. These have come so that the proven genuineness of your faith—of greater worth than gold, which perishes even though refined by fire—may result in praise, glory and honor when Jesus Christ is revealed. Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy, for you are receiving the end result of your faith, the salvation of your souls."
