What about the end times and the second coming?
The certainties are few and enormous: Christ will return personally, visibly and unexpectedly; the dead will be raised; there will be judgment; and He will make all things new. The schemes — pre-, mid- and post-tribulation, the identity of figures in Revelation — are where sincere Christians have always disagreed, and the New Testament's own application is never speculation or date-setting. It is always the same: watch, and live so that you would not be ashamed to be found doing what you are doing.
