"But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only. As were the days of Noah, so will be the coming of the Son of man. For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, and they did not know until the flood came and swept them all away, so will be the coming of the Son of man. Then two men will be in the field; one is taken and one is left. Two women will be grinding at the mill; one is taken and one is left. Watch therefore, for you do not know on what day your Lord is coming. But know this, that if the householder had known in what part of the night the thief was coming, he would have watched and would not have let his house be broken into. Therefore you also must be ready; for the Son of man is coming at an hour you do not expect." (Matthew 24:36-44)
"For the Lord [Jesus] himself will descend from heaven with a cry of command, with the archangel's call, and with the sound of the trumpet of God. And the dead in Christ will rise first; then we who are alive, who are left, shall be caught up together with them in the clouds to meet the Lord in the air; and so we shall always be with the Lord. Therefore comfort one another with these words. But as to the times and the seasons, brethren, you have no need to have anything written to you. For you yourselves know well that the day of the Lord will come like a thief in the night. When people say, 'There is peace and security,' then sudden destruction will come upon them as travail comes upon a woman with child, and there will be no escape. But you are not in darkness, brethren, for that day to surprise you like a thief. For you are all sons of light and sons of the day; we are not of the night or of darkness. So then let us not sleep, as others do, but let us keep awake and be sober. For those who sleep sleep at night, and those who get drunk are drunk at night. But, since we belong to the day, let us be sober, and put on the breastplate of faith and love, and for a helmet the hope of salvation. For God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ, who died for us so that whether we wake or sleep we might live with him. Therefore encourage one another and build one another up, just as you are doing." (1 Thessalonian 4:16-5:11)
