If Paul, who came along later, were to have been introducing an additional coming to the one in the olivet discourse, he would have been going against what Jesus had said. He would also have used very specific language setting forth this new thing, “Jesus is to return in two stages, not one like you have been led to believe,” or something similar, which he did not.
Jesus DID reveal to Paul a 'new coming'...It was a mystery up til the time of Paul...
1Co 15:51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
1Co 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
Jesus DID reveal to Paul a ‘new coming’...It was a mystery up til the time of Paul...
1Co 15:51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
1Co 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
>>There’s a trump sounded after the tribulation, Matt. 24:29-31, surely the last trump wouldn’t you say? You have Paul adding to Jesus’s words with a pretrib last trump. Nothing is said in the 1 Cor. passages you cited about the last trump taking place before the tribulation, you read that into the passage. It’s the same last trump as Jesus’.
That event is clearly the same second coming everyone else was expecting, because it happens at the last trump, exactly when John tells us the second coming occurs in Revelation.
Throughout history, there have been many prophecies that remained mysterious until they were partially or fully fulfilled. One of them was the dream shown by God to Nebuchadnezzar and interpreted by Daniel, of the gold, silver, brass, iron, and iron/clay picture that we are still living out.
The seventieth week of Daniel's vision was not seen clearly until seen by 18th-19th century Bible students. Not comprehended by earlier scholars and translators doesn't make these later seen truths wrong.
It only makes those who can't be taught as being closed-minded by their exclusive dependence on the philosophies of fallible dull humans, rather than on the truths of the Scriptures found by Spirit-illuminated believers.
But thanks for your support of this clear application of Paul's Gospel imparted by His tutor, Christ.
