first of all, there are alot of what ifs. what if this happened, what if that happened. there is no point speculating on the ifs ands or buts.
when the end comes, if it is in our lifetime, we will all see Jesus. the Bible states so.
no point in dwelling on the what ifs or what might happen or not happen. when He brings about the end is also unknown to us.
the best thing to do is to live your life pleasing to God and not worry about things that we have no control over.
take care about your salvation and do something to make sure you live a life that is pleasing to God.
