the end may not mean the very end but an end of an era or personal tribulation. the last book rev is over many 100s or years, if u look at the horseman 2 have happened according to history conquest and war and we are at the start of drought(or famine) with pestilence and plague still to come. the rapture or multitude isn't till the earth and heavens get shaken and then there is more after that, so if u are waiting for the rapture it may be a long wait
