sober. (1 Thess 5:2-9) Mt 24:14, Mt 24:36, Acts 1:6-7, 2 Pt 3:10, Mt 24:43, Lk 12:40, Rev 3:3, Rev 16:15, Mt 25:13

The end will come after the gospel has been preached all over the world. (Mt 24:14)

Mt 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.

We do not know when the Lord will come. (Mt 24:36, Mt 25:13, Acts 1:6-7)

Mt 24:36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.

Mt 25:13 Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.

Acts 1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? 7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.

The day of the Lord will come like a thief. We should be sober and watchful. In other words, the gospel will be spread rapidly throughout the world. And we will never know when the gospel was preached all over the world. Therefore, you must be awake. (Mt 24:41-44, Lk 12:40, 1 Thess 5:2-9, 1 Pt 3:10, Rev 3:3, Rev 16:15)

Mt 24:41 Two women shall be grinding at the mill; the one shall be taken, and the other left. 42 Watch therefore: for ye know not what hour your Lord doth come. 43 But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up. 44 Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh.

Lk 12:40 Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.

1 Thess 5:2 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,

1 Pt 3:10 For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile:

Rev 3:3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.

Rev 16:15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
