Tribulation Period

In short, the reason you want to to be watchful and prayerful and keep the word of His patience (Matt. 24.40-42, Luke 21.36, Rev. 3.10) is because if you don't you will not be received, taken or raptured at the first rapture "before the throne" (Rev. 7.9) before the first trumpet (8.7ff) of the Tribulation begins. Thus, you will pass through the Tribulation and be raptured at the last trumpet instead. And if you remain with that same attitude of not being ready, you will also not return with Christ (Jude 14,15) to reign over the nations (Rev. 2.26, 20.4-6) for the 1000 years. Thus, shall you be disciplined for 1000 years in "outer darkness" (having no fire or furnace about it) outside the light of rewards of reigning with Christ for the 1000 years. That's a long time as one of the 5 unwise virgins to lose rewards, not permitted to enter the marriage feast of the millennial first resurrection kingdom reign.

And the reason we know the Tribulation is Sept. 14, 2015 to Aug. 7, 2022 is because this is exactly 2,520 days required for 7 years x 360 days per year of Daniel's prophecy that is applied to the last 3 feasts pertaining to when Jesus returns with the first rapture on Feast of Trumpets and Jesus stepping down on the mount of olives on Tisha B'Av (1260th day) to reign in the Temple by the 1335th day (75 days after He steps down). The 1335th day is after the 3 feasts and on the 4th day of Simchat Torah (Oct. 18-21, 2022), the final celebration as a 4 day inspection. Simchat Torah is when Israel brings out the Torah Scroll to read as well to show forth the 3 items of the Ark of the Covenant: rod that budded, ten commandments and manna from heaven.

The Holy of Holies represents our spirit, the Holy Place our soul and the outer court our body. The Holy Spirit comes down and rests in our new spirit possesing eternal life. Our spirit has three functions exhibited in the Holy of Holies. We know the law of the Ten Commandments by our conscience that convicts us. We commune in our spirit with God as Hi Holy Spirit comes down across the cheribum to the mercy seat. Intuitively we know by what the Holy Spirit conveys to us His will by the law. And the 3 items in Ark represent the work of the Trinity: the rod that budded (Spirit's movement), manna from heaven to be eaten (word of God), and the Ten Commandments (given by the Father). The Ark of Testimony of God is not located in our soul or body but our spirit.

Within Premillennialism Futurism (Christian eschatology) affirm that the 2300 days of Daniel 8:14 have not yet occurred and refer to the future sacerdotal rites of a yet future Third Temple to be built during Daniel's Prophecy of Seventy Weeks - which also is yet future. The "reign of the Beast" (See: Abomination of Desolation) commences at the mid-point of Daniel's Prophecy of Seventy Weeks and thus ensues in "days" (as in the "evening and morning" (Daniel 8:14)) the 1290 days of "desolations" or "abominations" (Daniel 12:12). These "desolations" or "the host to be trampled underfoot" (Daniel 8:13) must be calculated by adding the days of the "daily sacrifices" in a restored Third Temple, yet future, to the "days of desolation" or 1010 (days of sacrifice) + 1290 (days of desolations) = 2300 days: "'How long will the vision be, concerning the daily sacrifices and the transgression of desolation, the giving of both the sanctuary and the host to be trampled underfoot?' and he said to me, 'For two thousand three hundred days; then the sanctuary shall be cleansed.'" These eschatologists conclude that the Prophecy of Seventy Weeks is directed to Jews in a regathered Israel in the "latter days" ("Seventy weeks are determined for your people and for your holy city" - Daniel 9:24).

From the 1260th day to the 1290th day is 30 days more after Jesus returns. Jesus casts His judgment over the nations for those 30 days more. After which time, 45 days more are needed to the 1335th day set up Israel as the center of all nations. If the 2300 days is to the 1260th day (not to the 1290th), then the Temple would be completed 1040 rather than 1010 days before the Great Tribulation starts. There would be an adjustment to the common thinking:

250 Days (From the commencement of Daniel's 70th Week - Period of Rebuilding the Third Temple) + 1010 Days (Period of Sacrifices) to the "Middle of the Week"and the "Abomination of Desolation" + 1290 Days of "Desolations" (Daniel 12:11) (which is equal to 2300 days - i.e., 1010+1290=2300 Days - which is 30 days beyond the conclusion of Daniel's 70th Week) + 45 Days or unto the 1335th Day (i.e., the period of the "judgment of the nations" and of the "unveiling of Messiah to National Israel" - Daniel 12:12)- total numbers of "days" involved: 250+1010+1290+45=2595
