What scripture teaches this?
It is verified by Ezekiel 39, after Gog/Magog, and 7 year later after the time of the Antichrist and the battle of Armageddon feast in Ezekiel 39:17-20. With Jesus having returned and reigning here on earth in
in verse 21, Jesus says.... in verse 23 and 24, identifies the transgression caused them to be slain by the sword, which the persecution of the Jews for the past 2000 years among the nations is unarguable.
17 And, thou son of man, thus saith the Lord God; Speak unto every feathered fowl, and to every beast of the field, Assemble yourselves, and come; gather yourselves on every side to my sacrifice that I do sacrifice for you, even a great sacrifice upon the mountains of Israel, that ye may eat flesh, and drink blood.
18 Ye shall eat the flesh of the mighty, and drink the blood of the princes of the earth, of rams, of lambs, and of goats, of bullocks, all of them fatlings of Bashan.
19 And ye shall eat fat till ye be full, and drink blood till ye be drunken, of my sacrifice which I have sacrificed for you.
20 Thus ye shall be filled at my table with horses and chariots, with mighty men, and with all men of war, saith the Lord God.
21 And I will set my glory among the heathen, and all the heathen shall see my judgment that I have executed, and my hand that I have laid upon them.
22 So the house of Israel shall know that I am the Lord their God from that day and forward.
23 And the heathen shall know that the house of Israel went into captivity for their iniquity: because they trespassed against me, therefore hid I my face from them, and gave them into the hand of their enemies: so fell they all by the sword.
24 According to their uncleanness and according to their transgressions have I done unto them, and hid my face from them. (Jesus wanted to keep them from being persecuted, but they refused him as their King, crucifying him, and then rejecting Him resurrected to be the Savior from their sins, removing their sins. Which was the transgression that sent them into 2000 years of exile and persecution. Which it will not end until Jesus returns. Ending the 70 weeks.)
Matthew 23:37 O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee,
how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!
Again, what scripture teaches this?
Matthew 23:39 For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.
All Christians are preterist. we only vary by degree.
I think you know what is meant between them who are preterists and them who are futurists..
