Elder Mark E. Petersen has offered the following explanation on conditions in the world as outlined in 1 Nephi 22:16-17:
… in these, the last days, the Lord has predicted that there shall be two simultaneous movements. One of these movements is the great tribulation that shall come upon the world. The wicked will destroy the wicked.The other great movement which will be going forward simultaneously is that there shall be a stone cut out of the mountain without hands, and it shall roll forth and eventually fill the whole earth. The Church to which you and I belong is that stone. It has been cut out of the mountain without hands, and your destiny and mine is to help roll it forth. (D&C 65:2.)
Now do you suppose for one moment that the judgments of God are going to interfere with the progress of his work? He is consistent, isn’t he? Although he will pour out his tribulations upon the wicked, he nevertheless will carry forward his work, and his people, under divine protection, will roll forth that stone until eventually it fills the whole earth.
And so says the Book of Mormon:
"For the time soon cometh that the fulness of the wrath of God shall be poured out upon all the children of men; for he will not suffer that the wicked shall destroy the righteous.
“Wherefore, he will preserve the righteous by his power, even if it so be that the fulness of his wrath must come, and the righteous be preserved, even unto the destruction of their enemies by fire. Wherefore, the righteous need not fear; for thus saith the prophet, they shall be saved, even if it so be as by fire.” (1 Nephi 22:16-17.)
I believe that. In the midst of all these tribulations God will send fire from heaven, if necessary, to destroy our enemies while we carry forward our work and push that stone until it fills the whole earth!
Your destiny is to do that very thing, and this is the kind of protection you will have. You do not need to fear about world conditions. You do not need to fear about anybody. Just serve the Lord and keep his commandments and build the kingdom, and as you do so you will be protected in these last days. God will have his hand over you, and you can plan your lives in confidence. (Conference Report, October 1960, pp. 81-83.)
