|Women in the wilderness.|
1 And it came to pass that we did again take our journey in the wilderness; and we did travel nearly eastward from that time forth. And we did travel and wade through much affliction in the wilderness; and our women did bear children in the wilderness.
2 And so great were the blessings of the Lord upon us, that while we did live upon raw meat in the wilderness, our women did give plenty of suck for their children, and were strong, yea, even like unto the men; and they began to bear their journeyings without murmurings.
3 And thus we see that the commandments of God must be fulfilled. And if it so be that the children of men keep the commandments of God he doth nourish them, and strengthen them, and provide means whereby they can accomplish the thing which he has commanded them; wherefore, he did provide means for us while we did sojourn in the wilderness.
The promise here is that if we keep the commandments, God will work incredible miracles to keep us strong and nourished. If you must live upon raw meat in the wilderness because you are keeping God's commandments, God will use it to make you strong.
If things really did Get Bad, there's no way a year of food storage would be enough. A year's supply for one person is maybe a few months' supply for a family. A family's food supply for a year would be a month or a few days for a community. But the point is obedience. By acting in faith, we show God that we are preparing our hearts to trust Him fully enough to provide for us in the wilderness.
Keep the commandments! Receive the blessings!
