The world is spiraling downward at an ever-quickening pace. I am sorry to tell you that it will not get better. I know of nothing in the history of the Church or in the history of the world to compare with our present circumstances. Nothing happened in Sodom and Gomorrah which exceeds in wickedness and depravity that which surrounds us now. Words of profanity, vulgarity, and blasphemy are heard everywhere. Unspeakable wickedness and perversion were once hidden in dark places; now they are in the open, even accorded legal protection. At Sodom and Gomorrah these things were localized. Now they are spread across the world, and they are among us.
We looked for the source and here it is: "The One Pure Defense" (an address to CES teachers in 2004)
Here's some more from his talk:
You, with the leaders and teachers in the priesthood and auxiliaries, are not the first line of defense. The family holds that line. Satan uses every intrigue to disrupt the family. There is “the shield of faith wherewith” the Lord said “ye shall be able to quench all the fiery darts of the wicked” (D&C 27:17).
This shield of faith is handmade in a cottage industry. What is most worth doing ideally is done at home. It can be polished in the classroom, but it is fabricated and fitted in the home, handcrafted to each individual. Many do not have support in the family. When that shield is not provided at home, we must, and we can, build it. You and the leaders and teachers then become the first line of defense.
He quoted a lot of scriptures:
In preparation for what is coming, the Lord warned, “In consequence of evils and designs which do and will exist in the hearts of conspiring men in the last days, I have warned you, and forewarn you, by giving unto you this word of wisdom by revelation” (D&C 89:4).
Paul prophesied, “In the last days perilous times shall come” (2 Timothy 3:1), then word by word and phrase by phrase, described exactly what our present conditions are now. He spoke of:
“Blasphemers, disobedient to parents, … unholy,
“Without natural affection, … incontinent, … despisers of those that are good,
“… lovers of pleasures more than lovers of God; …
“Ever learning, and never able to come to the knowledge of the truth,” and other things (2 Timothy 3:2–4, 7).
Which reminded Wayne of these scriptures:
13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15 And your feet shod with the preparation of the gospel of peace;
16 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
