Dear Ones - To have some extra food in reserve has been considered wisdom throughout all generations.  To have a food supply "put by" is a natural extension of all we do, on a daily basis, to meet the needs of our loved ones.  We've had such easy access to all we need, for several generations, that we have, in many cases, lost our (God-given) instinct for survival.
     As I've seen the matter discussed here, I've been content to "leave well-enough alone" and allow all the freedom to be led by the Holy Spirit.  But it has been troubling to me that some may have the impression that "gathering in against a day of trouble" equates to "hoarding."  Dear Ones, this is not so, and the use of that word is intimidating to those who want so much to not offend our Heavenly Father by seeming greedy or faithless.
     But I remind you that it was He who told us to "consider the ways of the ant," who made the squirrels and others to gather in nuts and food against harsh winters, who warned Joseph to gather in enough to last for seven years.  
    I know we have many wonderful examples, also, of his supernatural provision for his people when they were helpless, and we know that we can rely on his promises to provide for us, even to the point of his multiplying what we have (loaves and fishes) if it comes to that.  I believe with all my heart that my Heavenly Father can and will provide.
     My grandmothers also believed that, with all their hearts.  But every year, they faithfully gathered beautiful food from their gardens, and in labors of love, canned it and "put by" hundreds of glass jars filled with wonderful things to eat.  I remember going down the stairs into their cellars and seeing the shelves holding all those beautiful jars.
     That work was considered then, and still is now, by those who garden or buy with canning in mind, a virtuous and industrious work.  Would anyone have dreamed of calling it, or considering it, "hoarding?" Of course not.  Then consider:  Is having food in cans or bags from the grocery store on your shelves any more "hoarding" than having home-canned goods, or any of the other foods which people, since time immemorial, have had?   Are those who love to hunt and keep a freezer full of deer and turkey "hoarding?" Again, of course not. (No, that isn't me.  I don't hunt and I don't have a freezer - just an example :)
      If you have been afraid of offending God by buying some extra food and jugs of water, please be set free from such a misconception.  Remember wisdom.  Remember the Proverbs 31 woman.  Love from a sister in Jesus
