Many of us remember Elder Oaks timely message "Good, Better, Best" given in 2007. As I ponder on which things in life which are most needful - I think today of spiritual and temporal preparedness.
So, by way of Good, Better, Best; I would like to share my perspective as far as Home Storage is concerned.
Good would be: 2 weeks water, 3 month basic supply of food one would normally eat (plus a can opener etc.) and enough supplies, hygiene, first-aid, needed medicines etc.)
Better would be: 3 month supply of food, water, supplies (including fuel, clothing etc.), and some alternative ways of cooking etc. plus, one-year supply of grains and beans etc. and some basic recipes.
Best would be: All of the above plus knowledge of how to use them. Alternative ways of cooking. Tent in each home (as per suggested by Sis. Julie B. Beck; See: Self-Reliance March 2010). Knowledge (see resources on upper left of this site), Practice (see blogs on left side of this site part way down), Continual Learning, Obedience, Following Prophet no matter what, Having Spirit as our Guide, Heeding counsel, Living within means, Gardening, Preserving own food etc.
I know that the Lord helps us as we strive to obey what He has asked us to do.
1 Nephi 3:7 "...for I know that the Lord giveth no commandments unto the children of men, save he shall prepare a way for them that they may accomplish the thing which he commandeth them."
But, when we do not what He says; he sometimes cannot.
"I, the Lord, am bound when ye do what I say; but when ye do not what I say, ye have no promise." Doctrine and Covenants 82:10
Too often we bask in our comfortable complacency and rationalize that the ravages of war, economic disaster, famine, and earthquake cannot happen here. Those who believe this are either not acquainted with the revelations of the Lord, or they do not believe them. Those who smugly think these calamities will not happen, that they somehow will be set aside because of the righteousness of the Saints, are deceived and will rue the day they harbored such a delusion. - Ezra Taft Benson
