Prepping?? Hmm, because Jesus told us not to worry about tomorrow?? That says more about "worry" than prepping.
Consider:
1 Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom. 2 And five of them were wise, and five were foolish. 3 They that were foolish took their lamps, and took no oil with them: 4 But the wise took oil in their vessels with their lamps.
Matt 25:1-4 (KJV)
Is that not preparing?
Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time is at hand.
Rev 1:3 (KJV)
Is that not preparing?
Or perhaps when the Lord told Joseph, in Egypt, to store grain in preparation for the famine.
Is this the kind of stiff you're asking for?
