"...was cast into the lake of fire, the second death" death being the opposite of life.
More often than not, the Bible when prophesying the advents of Jesus, speaks of them as a continuous occurrence (the same with Bible prophecy). In Revelation chapter 20, verses 12 through 15 include a gap, but less than the gap between Jesus' two advents and the gap between prophecies' 'immediate' and 'latter day' fulfillments.
If the Hebrew Spring holy days prophesied Jesus' first advent (the Passover Lamb and single grain of sheaf waved in the air, etc) than surely the Autumn holy days of Trumpets, Day of Atonement and Tabernacles, prophecy His long second advent.
Between Trumpets and the Day of Atonement is "10" days and the millennial Kingdom of Jesus/restoration lasts "1000" years. Between the Day of Atonement and Tabernacles is "5" days suggesting the Day of Judgment/Atonement lasts "500" years, at the beginning of which occurs the second resurrection, the resurrection of all those who have died unbelieving (some never having "heard") and at the end of that 'day' is when God speaks the notorious words "those not believing will go to the second death". But after having experienced being resurrected, and experiencing, living through and witnessing a 500 years long day of the examination of all human history.. who is not going to believe after all that?
- The Fall holy days prophecying five hundred years between the Day of Judgment/Atonement and the day when "God comes to Tabernacle with man" (Revelation 21:3) hence a 500 years long day of Judgment/Atonement. [From Trumpets/Last Trump to Atonement to Tabernacles.]
If the Spring holy days were fulfilled by the first (and literal) advent, why not the second by Israel's Fall holy days?
