Jacob’s trouble is a term used once in scripture… Jer. 30:7. Because of the time of Jacob’s trouble produces a scattering of the people of Israel to the 4 winds, this time refers to 70 AD. Isaiah tells us that when Israel becomes a nation again it will never be scattered again. This happened in 1948. The time of Jacob’s trouble is an event of the past. Why then is it important for the time of “Jacob’s trouble” to be considered the great tribulation? For one reason and one reason alone. It is to separate Israel from the church so that the pretrib doctrine can exist. With the separation we can attempt to have Paul write to the Gentile church and Jesus address Israel. That is as long as we overlook Peter (2 Peter 3:10) who wrote to the Gentile church and gave them the same message the Jesus (Matthew 24:29-35) gives Israel.
