Watch, for ye know neither the day nor the hour wherein the Son of man cometh. Matthew 25:13
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. For as a snare shall it come on all them that dwell on the face of the whole earth. 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. The day of the Lord so cometh as a thief in the night. 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. But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day; we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober.
Luke 21:34-36. 1 Thessalonians 5:26.
