D&C 133

As the work of salvation is being hastened, the Lord describes how His work will proceed saying -

"...for this cause, that men might be made partakers of the glories which were to be revealed, the Lord sent forth the fulness of his gospel, his everlasting covenant, reasoning in plainness and simplicity—
58 To prepare the weak for those things which are coming on the earth, and for the Lord's errand in the day when the weak shall confound the wise, and the little one become a strong nation, and two shall put their tens of thousands to flight.
59 And by the weak things of the earth the Lord shall thrash the nations by the power of his Spirit."  (Doctrine and Covenants | Section 133:57 - 59)

I find it interesting the the gospel is found in plainess and simplicity where it can be taught and testified by the weak, contrary to the world thinking that the elite possesses all wisdom.

And of those that will not "receive" His servants (the weak and humble) and simple gospel truths, the -

"...the day cometh that shall burn as an oven, and all the proud, yea, and all that do wickedly, shall be stubble; and the day that cometh shall burn them up, saith the Lord of hosts, that it shall leave them neither root nor branch."  (Doctrine and Covenants | Section 133:64)

When those that think they are so wise wonder why they have been burnt as an oven -

"...this shall be the answer of the Lord unto them:
66 In that day when I came unto mine own, no man among you received me, and you were driven out.
67 When I called again there was none of you to answer; yet my arm was not shortened at all that I could not redeem, neither my power to deliver."  (Doctrine and Covenants | Section 133:65 - 67)

Therefore -

"...this shall ye have of my hand—ye shall lie down in sorrow.
71 Behold, and lo, there are none to deliver you; for ye obeyed not my voice when I called to you out of the heavens; ye believed not my servants, and when they were sent unto you ye received them not.
72 Wherefore, they sealed up the testimony and bound up the law, and ye were delivered over unto darkness.
73 These shall go away into outer darkness, where there is weeping, and wailing, and gnashing of teeth."  (Doctrine and Covenants | Section 133:70 - 73)
