Verses 39-40 “39And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through.
40Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.”
No one knows when the Lord will come. All of those who set dates for the Lord’s return are only guessing. Even the saved people in the Tribulation Period will not know when Jesus is coming in glory to establish His kingdom. We do not set dates for the Rapture of the Church, but we believe that it will probably happen sooner than most people think.
