Should Christians Be Preppers?

We live on several acres in the country. There are a ton of trees in our county that are very old. Limbs often simply fall to the ground, sometimes taking out electric wires. When that happens, electricity goes out. We knew of this possibility when we moved in so we had a plan that included buying a decent sized generator and installing a transfer plug so that when it happened, we could be back up and running in mere moments.
