... There is good Biblical reason to believe that the Tribulation will be preceded by a seven year period of plenty. The seven years of plenty that preceded the seven years of famine in the story of Joseph, as well as other instances of instructions to prepare for impending tribulation type events in the Hebrew Scriptures all establish a biblical principal of a period of preparation according to Divine Instruction. The Lord Jesus pointedly stated “Behold, I have forewarned you,” so the Church, as well as every believer, should consider themselves under His clear instruction to be alert, informed, prepared and prayerful about exactly that which will transpire during the Tribulation so, “...that you may have strength to escape all these things that are about to take place, and to stand before the Son of Man.” Luke 21:36. - 2016: 7 Years of Plenty to Prepare for the Tribulation [link to freestockphotos.com]

First some definitions:

Prosperity means nominal GDP growth of 3% or more for two consecutive quarters similar to how recession is defined as a decline in GDP for two consecutive quarters.

Effection means the time when a new presidents policies start to take effect.

Last quarter (April, May & June) was President Trumps effection and the first eclipse is when two successive quarters of GDP growth may be known to meet or exceed 3% i.e. Prosperity is known to have begun.

The second eclipse is when Prosperity may be known to have existed for a period of 7 years i.e. April 2017 to April 2024 is seven years. :)

Caveat GDP growth > 2.5 rounds to 3.
