I Peter 4:7

Be watchful, and strengthen the things which remain, that are ready to die.

The end of all things is at hand: be ye therefore sober, and watch unto prayer.—Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.—Take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life.—The just shall live by faith: but if any man draw back, my soul shall have no pleasure in him. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.

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.

Man that is born of a woman is of few days, and full of trouble. He cometh forth like a flower, and is cut down: he fleeth also as a shadow, and continueth not.—The world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.—As in Adam all die, even so in Christ shall all be made alive. Death is swallowed up in victory.—Whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord’s.—To live is Christ, and to die is gain.

Cast not away . . . your confidence, which hath great recompence of reward. For ye have need of patience, that, after ye have done the will of God, ye might receive the promise. For yet a little while, and he that shall come will come, and will not tarry.—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.—The end of all things is at hand: be ye therefore sober, and watch unto prayer.

I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away.

The heavens and the earth, which are now, . . . are kept in store, reserved unto fire against the day of judgment.
