May quote scripture for this one?
Mark 13:
32¶But of that aday and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
34For the Son of man is as a man taking a far journey, who left his house, and gave aauthority to his servants, and to every man his work, and commanded the porter to watch.
35Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cock crowing, or in the morning:
There is much remaining to be fulfilled before the Lord can come. But in terms of the Lord coming to us, it is true, He could come tomorrow as we don't know when our last breath will be. This in mind, we needn't think that we can watch for the signs and repent in due time because as Paul said, we stand in jeopardy every hour because we don't know when our life will end and we will no longer have time to repent. If you wish to see a full listing of the commentary of the Lord's coming according to the LDS faith, you can check out my blog "Latter Day Musings" posted on the side of this blog. But for now, I can only say I believe the declaration of May 21st to be premature. I won't say more here as this is my secular satirical blog, but "mine other plates" are filled with the things of God. Link here
