“And then shall appear the sign of the Son of man in heaven: and _then shall all the tribes of the earth mourn_, and they shall see the Son of man coming in the clouds of heaven with power and great glory.” Matt. 24:30. “Behold, He cometh with clouds; and every eye shall see Him, and they also which pierced Him: and _all kindreds of the earth shall wail because of Him_.” Rev. 1:7. 4. Why will many not be prepared for this event? “But and if that evil servant shall say in his heart, _My lord delayeth his coming_; and shall begin to smite his fellow servants, and to eat and drink with the drunken; the lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of, and shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth.” Matt. 24:48-51. 5. What will the world be doing when Christ comes? “But as the days of Noe were, so shall also the coming of the Son of man be. For as in the days that were before the flood _they were eating and drinking, marrying and giving in marriage_, until the day that Noe entered into the ark, and knew not till the flood came, and took them all away; so shall also the coming of the Son of man be.” Verses 37-39. “Likewise also as it was in the days of Lot; _they did eat, they drank, they bought, they sold, they planted, they builded_; but the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all. Even thus shall it be in the day when the Son of man is revealed.” Luke 17:28-30. NOTE.—The idea is, not that it is wrong in itself to eat, drink, marry, buy, sell, plant, or build, but that men’s minds will be so taken up with these things that they will give little or no thought to the future life, and make no plans or preparation to meet Jesus when He comes. 6. Who is it that blinds men to the gospel of Christ? “In whom _the god of this world_ hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, which is the image of God, should shine unto them.” 2 Cor. 4:4.
