Once it sinks into the minds of a multiplied number of Left Behind individuals that Jesus has literally come to get the readied saints and gone back to Heaven, it will be a traumatic moment of heartbreak and regrets. The idea of an Antichrist and the number 666 is understood by millions of people. Most of these do not live a surrendered life to Jesus Christ.
Many people are religious, but show no evidence of being truly born again.
Even among the religious of our day, the fear of the God is almost totally absent. There is a kind of religious facade that has come to characterize this present generation. Preaching the words of God, like Billy Sunday and D. L. Moody, etc., is utterly rejected by the church world. Many people literally hate old-fashioned ministers. Suddenly, without warning, the Lord will descend into the clouds and the harvest of the earth will occur in a split second.
