That was one example of the Lord working in Joseph's (and therefore Israel's) life. I do not believe that is the Lord instructing all of us to hoard seven years' worth of provisions. Nowhere else in the Bible does God tell anyone but Joseph to do that.
Joseph’s revelation was literally for the “salvation” (physically) of the whole surrounding world - not for himself or even just the Jews - but also the Egyptians and surrounding countries.
This post is a good word.
I have no problem with prepping with two balancing thoughts:
1. Spiritual preparation is primary, not physical. Physical preparation without the spiritual is vanity that will be short-lived. Most people cannot afford to physically prepare - will God take care of them who cannot prepare physically but who are prepared spiritually? Of course. He always has.
2. If your preparation is just for yourself, and doesn’t include others - woe unto you when things collapse. Will you deny helping your own family? your friends? your neighbors? you will die alone....maybe last, but alone. Selfishness (really, “self”) is the root of all sin. It is not a virtue. Sacrifice for others is virtue. “No greater love.....”
7 years is NOT the issue.
The point is instructive to not waste times of plenty, but store up for times of need.
