Revelation 1:7

7 But the end of all things is at hand: be ye therefore sober, and watch unto prayer.
8 And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins.

8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
10 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.
11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.

20 He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
21 The grace of our Lord Jesus Christ be with you all. Amen.

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

26 And then shall they see the Son of man coming in the clouds with great power and glory.
27 And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
