It is of the greatest service to us all to be reminded that our life is but a vapor, which appeareth for a little while and then vanisheth away. Through forgetfulness of this worldlings live at ease, and Christians walk carelessly. Unless we watch for the Lord’s coming, worldliness soon eats into our spirit as doth a canker. If thou hast this world’s riches, believer, remember that this is not thy rest, and set not too great a store by its comforts. If, on the other hand, thou dwellest in straitness, and art burdened with poverty, be not too much depressed thereby, for these light afflictions are but for a moment, and are not worthy to be compared with the glory which shall be revealed in us.
Look upon the things that are as though they were not. Remember you are a part of a great procession which is always moving by; others come and go before your own eyes, you see them, and they disappear, and you yourself are moving onward to another and more real world.... Our duty is to trim our lamps against the time when the Bridegroom comes; we are called upon to stand always ready, waiting for the appearing of our Lord and Savior Jesus Christ, or else for the summons which shall tell us that the pitcher is broken at the fountain, and the wheel broken at the cistern, that the body must return to the earth as it was, and the spirit unto God who gave it.
From a sermon by Charles Haddon Spurgeon entitled "Stephen's Death," delivered May 24, 1874.
Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom. And five of them were wise, and five were foolish. They that were foolish took their lamps, and took no oil with them: But the wise took oil in their vessels with their lamps. While the bridegroom tarried, they all slumbered and slept.
And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him. Then all those virgins arose, and trimmed their lamps. And the foolish said unto the wise, Give us of your oil; for our lamps are gone out. But the wise answered, saying, Not so; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves.
And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut. Afterward came also the other virgins, saying, Lord, Lord, open to us. But he answered and said, Verily I say unto you, I know you not.
Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.---(Matthew 25:1-13)
