Jesus Christ Will Not Come to the Saints as a Thief
1 Thessalonians 5:1–8
1 But of the times and the seasons, brethren, ye have no need that I write unto you.
2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
4 But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6 Therefore let us not sleep, as do others; but let us watch and be sober.
7 For they that sleep sleep in the night; and they that be drunken are drunken in the night.
8 But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation.
President Joseph Fielding Smith said:
“I do not know when He is going to come. No man knows. Even the angels of heaven are in the dark in regard to that great truth [see Matthew 24:36–37]. But this I know, that the signs that have been pointed out are here. The earth is full of calamity, of trouble. The hearts of men are failing them. We see the signs as we see the fig tree putting forth her leaves; and knowing this time is near, it behooves me and it behooves you, and all men upon the face of the earth, to pay heed to the words of Christ, to His Apostles and watch, for we know not the day nor the hour. But I tell you this, it shall come as a thief in the night, when many of us will not be ready for it.”
