It is a hard task to understand what Christ and early christians had in mind. But I noted that in the Gospels appears the word "elect" (greek eklektos). It seems that early christians thought that they were chosen by God. But if they thought that they were chosen, it means that not all people had the same opportunity to gain salvation. So, early christian thought they were in a vip club. For instance:
if you continue in your faith, established and firm, and do not move from the hope held out in the gospel. This is the gospel that you heard and that has been proclaimed to every creature under heaven, and of which I, Paul, have become a servant. (Col 1:23)
Were not indians in the American Continent (Mexico, Peru, north america)?...what about chinese people ? So it seems that Paul thought that the END was very close and the earth was flat, in which only Europe, Asia and Africa existed. Note that only 1400 years later, american indians knew about Jesus and were forced to believe in the Catholic Faith. Furthermore, a later addition in Mark said:
Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. (Mark 16:16)
If I believe, this means that I choose to believe and not that I have been chosen. Worse, if I don't believe, I will be condemned. So, those american indians who rejected the Spanish Catholic priests who forced them with guns to believe in Jesus, will be condemned.
On the other hand, suppose that Mark told us accurately what Christ said in chaper 13. So, we have this statement:
And except that the Lord had shortened those days, no flesh should be saved: but for the elect's sake, whom he hath chosen, he hath shortened the days. (Mark 13:20)
This statement makes sense only if you want to save the flesh of the elect on earth. However, Paul said that the elect will meet Jesus in the air and so they always be (2 Th. 4:17).
For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect. (Mark 13:22)
So, if the elect can be seduced by signs and wonders, why God permits false prophets to do those great miracles?
And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven. (Mark 13:27)
I can hardly understand it. But may be it means that the elect will be taken from the earth to be led to heaven, but it contradicts verse 20.
WHAT A MESS !!!
