It says the end will come....not that Jesus would return....art the imminent rapture.I believe the Lord's return is impending, not imminent. Imminent suggests something is immediately about to happen, impending simply suggest approaching - whether near or far. None of the predictions in Rev were imminent or they would have happened 2000 years ago. At Pentecost the Gospel still hadn't gone out to the Gentiles. Christ couldn't come until it had gone to all nations. How could it have been imminent (any moment)?
14 And this gospel of the kingdom will be proclaimed throughout the whole world as a testimony to all nations, and then the end will come.
