Should we hoard up food for the coming times of judgment?
No. God will provide for us as he provided for Elijah in his time.
1 Kings 17:4 "And it shall be, that thou shalt drink of the brook; and I have commanded the ravens to feed thee there. 5 So he went and did according unto the word of the Lord: for he went and dwelt by the brook Cherith, that is before Jordan. 6 And the ravens brought him bread and flesh in the morning, and bread and flesh in the evening; and he drank of the brook."
"For two years past, the Lord has shown me in vision, repeatedly, that it is contrary to the Bible to make any provision for our temporal wants in the time of trouble. I saw that if the saints have food laid up by them, or in the fields, in the time of trouble when sword, famine, and pestilence are in the land, it will be taken from them by violent hands and strangers would reap their fields. Then will be the time for us to trust wholly in God, and he will sustain us. I saw that our bread and water would be sure at that time, and we should not lack, or suffer hunger.—The Lord has shown me that some of his children would fear when they see the price of food rising, and they would buy food and lay it by for the time of trouble. Then in a time of need, I saw them go to their food and look at it, and it had bred worms, and was full of living creatures, and not fit for use." {Broadside2 January 31, 1849, par. 9}
