I think you nailed it brother. Be ready, and we don't know exactly when. We can only see the fulfillment of all He said to watch for. And, we even disagree about all of those. The wise will be watching and ready, whether we leave personally by death, or are alive when He returns, and put on immortality then.
Personally I believe that is also why we can not claim any one church, with all of its doctrines, to be the 'only one'. There is plenty of pride and condemnation going around as it is. There would be even more hate and such then. One only needs to look at the ones who do so now. There are the faithful, true believers in every part of His body.
