I didn't, but I did find two other non-official ones - from an Elder Black in Argentina in 2014 and from a Sister Moss in Missouri in 2015. I, too, felt the change of perspective that Sister Moss mentions.
I also learned something from a good friend of mine who recently went to a mission conference with D. Todd Christofferson. He said that many people think that the SecondCcoming will come when the world is wicked enough. But this is not the case! The world already is wicked enough. The second coming will come when there are enough disciples that will accept Christ when he comes. We are not on the mission to show Heavenly Father how wicked these people are. We are here to find the righteous and prepare them for when Christ comes. - Elder Black
One night, a few sisters and I were talking to one of the senior couples in the VC and talking about the world. With the whole same-sex marriage supreme court thing, we were talking about how the world is becoming more and more wicked. And I just asked, why can't the Second Coming happen? Why do we have to wait, isn't the world wicked enough? Elder Phillips said that Elder Christofferson said that the world is plenty wicked for the Second Coming, but we are not righteous enough. That changed my perspective SO much. We have to be more righteous right now because we are literally paving the path of Christ to come reign on the earth. And we aren't righteous enough for that to happen. Elder Phillips said that President Vest told them we have to "crank our testimonies up". We got a lot of work ahead of us, people. - Sister Moss
Elder D. Todd Christofferson did give a conference talk that showed up in the Google search - Come to Zion, - in 2008. In it he said:
Zion is Zion because of the character, attributes, and faithfulness of her citizens. Remember, “the Lord called his people Zion, because they were of one heart and one mind, and dwelt in righteousness; and there was no poor among them” (Moses 7:18). If we would establish Zion in our homes, branches, wards, and stakes, we must rise to this standard. It will be necessary (1) to become unified in one heart and one mind; (2) to become, individually and collectively, a holy people; and (3) to care for the poor and needy with such effectiveness that we eliminate poverty among us. We cannot wait until Zion comes for these things to happen—Zion will come only as they happen.
Yes, we do need to prepare; we need to work on increasing our personal righteousness on a daily basis. Here's the link to an old seminary video that really impressed me the first time I saw it - The Gardener. It's a good question to ponder frequently - "Am I ready for the owner to visit his garden today?"
Visitor: Well, for not knowing when he's coming you certainly keep this place beautifully. You'd think you were expecting [the owner] tomorrow.
Caretaker: No. Today, sir, today.
Adding a couple more quotes:
"How do you prepare for the Second Coming? Well, you just don't worry about it. You just live the kind of life that if the Second Coming were to be tomorrow you would be ready. Nobody knows when it is going to happen. . . . Our responsibility is to prepare ourselves, to live worthy of the association of the Savior, to deport ourselves in such a way that we would not be embarrassed if he were to come among us. That is a challenge in this day and age."
President Gordon B. Hinckley,
Utah State Devotional, 1997;
quoted in Church News 2 January 1999,
or D&C Teacher Manual page 115
"We face some difficult days, the like of which we have never experienced in our lives. And those days are going to require faith and testimony and family unity. . . There should be no doubt . . . that the human family is headed for trouble. There are rugged days ahead. It is the time for every man who wishes to do his duty to get himself prepared - physically, spiritually, and psychologically - for the task which may come at any time, as suddenly as the whirlwind."
