take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life,

 And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares. Luke 21:34

And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed. The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light. Let us walk honestly, as in the day; not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying. But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof. Romans 13:11-1 

Therefore let us not sleep, as do others; but let us watch and be sober. 1 Thessalonians 5:6

But the end of all things is at hand: be ye therefore sober, and watch unto prayer. 1 Peter 4:7

For as a snare shall it come on all them that dwell on the face of the whole earth. Luke 21:35

 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. 1 Thessalonians 5:2 

But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. 2 Peter 3:10

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. Revelation 3:3

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

 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man. Luke 21:36

Watch therefore: for ye know not what hour your Lord doth come. Matthew 24:42

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

Heaven and earth shall pass away: but my words shall not pass away. But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.Take ye heed, watch and pray: for ye know not when the time is. For the Son of Man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch. Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning: Lest coming suddenly he find you sleeping. And what I say unto you I say unto all, Watch. Mark 13:31-37

And he spake a parable unto them to this end, that men ought always to pray, and not to faint; Luke 18:1
