Now Paul was talking to every age of the Church, as the time of the end had already been locked up in Daniel, so Paul didn't know exactly when it was going to be seen, but he did know that before it was, the dead in Christ would rise first, and then the gathering together in the twinkling of an eye would take place, and then the great tribulation would begin. John confirms this in Revelation. And Daniel is the timekeeper at the bell, or trumpet if you prefer. Now we are way down the road of prophecy since the Professor's article. The world has met on the problem and a decision is about to be rendered.
Scripture says that it's peace, followed by war.
And, they are right up against a wall of time. All we can do is stay alert, and warn our friends. Just shake and wake them to Paul's teaching to the Thessalonians. But, if this is not the year, then that gives us more time to continue in our work of watching and alerting. The dead that rise on First Fruits will do the warning when it's time.
