What Scripture is unfulfilled?
Depends upon who you adhere to I suppose. Preachers will tell you just about anything. I tend to read the Book. As a textual critic, I see contracts there - And those contracts rely upon completion. One does not necessarily supersede the other, but each contract requires exact fulfillment, as contracts always do. Each of those contracts has a prophecy in the way of a prophecy or set of prophecies as a downpayment on each deal - So those prophets needfully must see fulfillment, or God is not god.
And secondly - whole rafts f prophecy that the churches pay no mind to have to have already happened - without anyone notable catching on - The prophecies toward Ephraim are a brilliant example - Roughly a third of the Bible is dedicated to prophecies toward Ephraim and must necessarily come true... Necessarily must have come true by now in large part - But everyone shrugs their shoulders, oblivious to the implications. Even so, while much of it must have already happened, still a portion cannot have happened.
Likewise the 'Binding of the Sticks' in Ezekiel, whole swaths of Zechariah and Isaiah, much is left undone
I haven't missed Him.
If he has not come, then all is not fulfilled. If you are not in your heavenly body (I know I ain't) then all is not fulfilled. If you have not stood before the Bema Seat - Then all is not fulfilled. These are not matters of interpretation. They are necessary elements. Much of the Apocalypse remains undone. The earth is not renewed. The evil are not reduced to ashes... I could go on and on.
Jesus Christ is the New Covenant and New Law, meaning that He has fulfilled the purpose of the Old Covenant and the Old Law. Jesus is also the fulfillment of the Old Testament roles of rabbi, prophet, and king.
The 'new law' employs the old. Necessarily the law and the mercy both be efficacious, because without the law, there is no need for mercy. And without the mercy, no one would survive the law. And it makes no difference - The new does not supplant the old. They must fit together, but stand alone. Once one reads it with that in mind, your suppositions flee.
The way it must lock together resolves interpretation. Each contract must be honored completely. Yah's word does not return to him empty - Empty in any small part, and that part awaits fulfillment.
But all of that borders on the religious exemption for this forum, so I do not want to go on. If you wish to continue this inquiry, I will be happy to go at it tooth and nail by PM.
My point is that evil is rising yet again - Likely for the end game at this late date. Just as it has before. It is far more likely that the same perpetrators are behind it as the last time and the time before, and the time before.
That evil is not interplanetary travelers. It is the same inter-dimensional beings as always... With the same shtick. People would really do well to read history.
