If something happens to the world, we're going to need the 5 G's.
God, gold, guns, grains, ground.
To explain further:
God: Being right with God, being in the state of grace, having good religious books, sacramentals, etc. in your possession
Gold: Precious metals and other material things that will be worth their weight in gold after a collapse scenario. This includes practical items like shovels, seeds, lumber, concrete blocks, gasoline, diesel, rope, etc.
Guns: Weapons to defend yourself, your family, and your stuff from the desperate, wild hordes (who will not be bound by any sort of morality) who didn't prepare at all. If you think "I'll just be passive and peaceful", I'll just say one word that will cause you to go out and buy some serious guns: Rape. Would you be able to stand by and helplessly watch while your wife, sister(s), mother, or daughter(s) got raped? Neither would I.
Grains: Food and water, and the means to produce more of these. Gardening equipment would fall in here.
Ground: A piece of land where you can ride out the worst of it -- preferably outside the city. Also a place to grow food, even if it's not huge.
