You can't predict the date. But we have been given signs. Matthew 24 gives a short overview of what's to come: False Christs (Jesus of Siberia, Jose de Jesus Miranda, Maitreya, David Icke, etc.) False prophets (Joseph Smith, and more recent Benny Hinn as well as those who falsely predicted the rapture), As well as natural disasters such as earthquakes, pestilences, and floods [Luke 21:11]. That's just the beginning of it.Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
—2 Peter 3:3-4
But as the days of Noe[Noah] were, so shall also the coming of the Son of man be. —Matthew 24:37
Just as in the days of Noah, there will be scoffers. People mocked Noah for building an ark and believing in a flood, as a result they were not saved. Sin was rampant in those days, and immorality is on the rise in this generation.
What has been will be again, what has been done will be done again; there is nothing new under the sun —Ecclesiastes 1:9
And it can get a lot worse as it already has.
But of that day and that hour knows no man, no, not the angels who are in heaven, neither the Son, but the Father. —Mark 13:32
