Here is further biblical support for prepping. These are just my humble thoughts on how these verses may be interpreted:
BIBLICAL SUPPORT FOR PREPAREDNESS
“Now therefore let the king provide a wise and industrious man, and make him ruler over the land of Egypt: that he may appoint overseers over all the countries: and gather into barns the fifth part of the fruits, during the seven fruitful years, that shall now presently ensue: and let all the corn be laid up under Pharao's hands and be reserved in the cities. And let it be in readiness, against the famine of seven years to come, which shall oppress Egypt, and the land shall not be consumed with scarcity.”
Genesis 41:33
This refers to the responsibility to take a leadership role and to be “wise and industrious” in the care of the people who rely on you.
“Give not sleep to thy eyes, neither let thy eyelids slumber. Deliver thyself as a doe from the hand, and as a bird from the hand of the fowler. Go to the ant, O sluggard, and consider her ways, and learn wisdom: which, although she hath no guide, nor master, nor captain, provideth her meat for herself in the summer, and gathereth her food in the harvest. How long wilt thou sleep, O sluggard? When wilt thou rise out of thy sleep? Thou wilt sleep a little, thou wilt slumber a little, thou wilt fold thy hands a little to sleep: And want shall come upon thee, as a traveller, and poverty as a man armed. But if thou be diligent, thy harvest shall come as a fountain, and want shall flee far from thee.”
Proverbs 6:4
This is a strong admonition to take care of your own needs through discipline and hard work.
“There is a treasure to be desired, and oil in the dwelling of the just: and the foolish man shall spend it.”
Proverbs 21:20
The holy, who live a good life, performing their duties and exercising prudence, will be blessed with abundance.
“The prudent man saw the evil, and hid himself: the simple passed on, and suffered loss.”
Proverbs 22:3
When you see the threat looming, you must take action.
“Cast thy bread upon the running waters: for after a long time thou shalt find it again. Give a portion to seven, and also to eight: for thou knowest not what evil shall be upon the earth. If the clouds be full, they will pour out rain upon the earth.”
Ecclesiastes 11:1
Think ahead, plan ahead and watch the signs around you.
“In the morning sow thy seed, and in the evening let not thy hand cease: for thou knowest not which may rather spring up, this or that: and if both together, it shall be the better.”
Ecclesiastes 11:6
Work harder than you think you need to, for some of your work may not bear fruit.
“For I know the thoughts that I think towards you, saith the Lord, thoughts of peace, and not of affliction, to give you an end and patience.”
Jeremias 29:11
Though calamity may come, God will preserve many of His children (so we must never give up and keep trying to survive).
“Hear the word of the Lord, ye children of Israel, for the Lord shall enter into judgment with the inhabitants of the land: for there is no truth, and there is no mercy, and there is no knowledge of God in the land. Cursing, and lying, and killing, and theft, and adultery have overflowed, and blood hath touched blood. Therefore shall the land mourn, and every one that dwelleth in it shall languish with the beasts of the field, and with the fowls of the air: yea, the fishes of the sea also shall be gathered together.”
Hosea 4:1
When immorality abounds, we may expect a great chastisement to come.
“And there came to him the Pharisees and Sadducees tempting: and they asked him to shew them a sign from heaven. But he answered and said to them: When it is evening, you say, it will be fair weather, for the sky is red. And in the morning: Today there will be a storm, for the sky is red and lowering. You know then how to discern the face of the sky: and can you not know the signs of the times?”
Matthew 16:1
We must be watchful and understand the implications of what is happening in the world.
“And from the fig tree learn a parable: When the branch thereof is now tender, and the leaves come forth, you know that summer is nigh.”
Matthew 24:32
Again, we are told to observe the signs around us and be prepared for what surely will come.
“Watch ye therefore, because ye know not what hour your Lord will come. But know this ye, that if the goodman of the house knew at what hour the thief would come, he would certainly watch, and would not suffer his house to be broken open. Wherefore be you also ready, because at what hour you know not the Son of man will come. Who, thinkest thou, is a faithful and wise servant, whom his lord hath appointed over his family, to give them meat in season. Blessed is that servant, whom when his lord shall come he shall find so doing. Amen I say to you, he shall place him over all his goods.”
Matthew 24:42
This probably refers more to spiritual preparedness, always our primary concern, though there is a reference to the temporal.
“And he brought him to Jerusalem, and set him on a pinnacle of the temple, and he said to him: If thou be the Son of God, cast thyself from hence. For it is written, that He hath given his angels charge over thee, that they keep thee. And that in their hands they shall bear thee up, lest perhaps thou dash thy foot against a stone. And Jesus answering, said to him: It is said: Thou shalt not tempt the Lord thy God.”
Luke 4:9
When signs are clear that danger is looming, we must not remain complacent that God will take care of us, but do what we can to help ourselves and others (then trust in God for what we cannot control).
“But if any man have not care of his own, and especially of those of his house, he hath denied the faith, and is worse than an infidel.”
1 Timothy 5:8
This is an admonition to provide well for those in our care, which includes having the foresight to see when we must prepare for difficult times.
