I am concerned by your chart because you are sure we will be raptured before tribulation starts. I am hopeful you are correct but after going through the John Shorey book, The Window of the Lords Return 2012-2020, I would like you to compare his conclusion with yours.
I have looked at the link you sent to the Lord’s return book. The author does not distinguish Paul’s Apostleship from the 12 Apostles. Certainly what the Lord taught them was that they were facing the tribulation because they were looking for and preaching the gospel of the Kingdom – Jesus Christ setting up his Kingdom here on earth and sitting on the throne of David in Jerusalem.
Paul was given the revelation of the Dispensation of the Grace of God for us Gentiles who live in this age. According to Ephesians and Colossians (even all of Paul’s Epistles) “we are made to sit together in heavenly places that in the ages to come …” (Ephesians 2:6,7). The reason for the rapture is to take us into the “heavenly places.” According to Revelation 12 in the middle of the tribulation Satan and his angels are cast out of heaven and their place is no more found. That is because we have replaced them. We are there before they are cast out because God prepared us for those positions so they would not be left void. Keep looking for the blessed hope (Titus 2:13,14) not for a sign.
