Amos 8:11 Behold, the days come, saith the Lord God, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the Lord:
12 And they shall wander from sea to sea, and from the north even to the east, they shall run to and fro to seek the word of the Lord, and shall not find it.
13 In that day shall the fair virgins and young men faint for thirst. 14 They that swear by the sin of Samaria, and say, Thy god, O Dan, liveth; and, The manner of Beersheba liveth; even they shall fall, and never rise up again.
Since the Lord God is sending the famine of the Word of God in the land, it would explain why the Lord will come like a thief in the night after all since many saved believers will be found in darkness to be left behind for not being ready to go.
1 Thessalonians 5:1But 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.
9 For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ,
10 Who died for us, that, whether we wake or sleep, we should live together with him.
11 Wherefore comfort yourselves together, and edify one another, even as also ye do.
