>> the perfect ending was the crucifixion and resurrection of Jesus Christ. He was the main event, not a side event.
Respectfully —
As you say, Jesus CHRIST is THE “main thing”. Genesis to Revelation, the Word of GOD is all about Him. In fact, He IS the Word of GOD.
But the WORD tells us that His resurrection is in no way the “perfect ending”. He is the FIRSTborn of a great harvest of GOD’s children. GOD wants a big family!
And Jesus WILL come again to bring his brothers and sisters home. THAT’s the “perfect ending”.
In conjunction with that glorious Advent the Close of the Age must occur, as prophesied, and that unfolding of the final chronology of GOD’s Plan absolutely concerns Israel as well as the Body of CHRIST.
There is no ending.
But there will be a ‘new’ beginning.
When in Revelation it is revealed that God will bring New Jerusalem to earth to replace the Jerusalem we know now.
It’s going to be gigantic (see the measurements in the Book of Revelation) with Many Mansions.
Enough for all of us!
To live for ever in the Kingdom of God, worshiping God day and night.
