JST - Matthew 24

The Lord tells us why we are given the signs of the times of the last days explaining -

"Behold I speak for mine elect's sake..."  (Pearl of Great Price | JS-Matthew 1:29)

And then He adds -

Now learn a parable of the fig-tree—When its branches are yet tender, and it begins to put forth leaves, you know that summer is nigh at hand;
39 So likewise, mine elect, when they shall see all these things, they shall know that he is near, even at the doors..."  (Pearl of Great Price | JS-Matthew 1:38 - 39)

That is why His work has been hastened for -

"...this Gospel of the Kingdom shall be preached in all the world, for a witness unto all nations, and then shall the end come, or the destruction of the wicked..."  (Pearl of Great Price | JS-Matthew 1:31)

And those that are not deceived but overcome the world, shall be gathered and saved for, using a parable  -

"...Behold, wheresoever the carcass is, there will the eagles be gathered together; so likewise shall mine elect be gathered from the four quarters of the earth."  (Pearl of Great Price | JS-Matthew 1:27)

Where -

"Then shall be fulfilled that which is written, that in the last days, two shall be in the field, the one shall be taken, and the other left;
45 Two shall be grinding at the mill, the one shall be taken, and the other left..."  (Pearl of Great Price | JS-Matthew 1:44 - 45)

That is seeking our the righteous where ever they may be. 

And as a word of warning -

"...again shall the abomination of desolation, spoken of by Daniel the prophet, be fulfilled."  (Pearl of Great Price | JS-Matthew 1:32)

I don't know if this prophesied "abomination" is one type of iniquity or an accumulation of iniquities, but as a warning, the wicked will become desolate.  My intuition is because -

"...the love of men shall wax cold..."  (Pearl of Great Price | JS-Matthew 1:30)

Where all they think about is their own gratification.
