If I am not mistaken, you have a debate coming up with Don Preston. While my position is closer to Don's, I strongly disagree with the full preterist hermeneutic that demands that all Bible prophecy was fulfilled by AD 70. I think it will be helpful if you have a solid answer in response to Luke 21;22. Maybe you already do but just in case I wanted to put my two cents in.
LUKE 21:22: DID JESUS TEACH THAT ALL PROPHECY WOULD BE FULFILLED AT AD 70?
Luke 21:22 is one of the foundations of the full preterist paradigm of all prophecy being fulfilled by AD 70; as such it deserves careful consideration:
This is a clear reference to the AD 70 destruction of Jerusalem. Full preterists maintain that the "all things" referred to here means that all the prophecy in the Bible would be fulfilled at this time. This is simply incorrect. What Luke 21:22 is saying is that all the things written about the days of vengeance on God’s disobedient old covenant people would be fulfilled by AD 70, not that all Bible prophecy would be fulfilled at that time. The meaning of Luke 21:22 is important; it has a major impact upon the full preterist’s interpretive framework. Any scripture that a full preterist comes upon is assumed to have been fulfilled by or before AD 70; full preterists have to come to this conclusion or abandon their paradigm. In this sense the belief in all prophecy fulfilled by AD 70 functions much like a creed for full preterists.But when you see Jerusalem surrounded by armies, then know that its desolation is near. Then let those who are in Judea flee to the mountains, let those who are in the midst of her depart, and let not those who are in the country enter her. For these are the days of vengeance, that all things which are written may be fulfilled.
Luke 21:20-22
In terms of the subject of Luke 21:22 (i.e., the days of vengeance), there are a number of passages that speak of God's vengeance on his old covenant people when they broke the covenant. The two major sections are found in Leviticus 26 and Deuteronomy 28-32. The days of vengeance were to involve God bringing a sword (i.e., a nation) against his unfaithful old covenant people in retribution for their breaking the covenant. This would result in God’s old covenant people being scattered among the nations.
In Luke 21:22 Jesus is saying that all the covenant punishments spoken of in Leviticus and Deuteronomy would be fulfilled at the AD 70 desolation of Jerusalem (Luke 21:20; cf. Matt. 23:32-36) and that the Jews would be scattered to the nations. He was not saying that all Bible prophecy would be fulfilled at this time. While God's old covenant people had been judged before for breaking the covenant (cf. Dan. 9:10-13), the ultimate judgment would come in AD 70; it would be focused on the generation that rejected Jesus and had him killed. This is because the murder of Jesus was the ultimate act of breaking the covenant (cf. Matt. 21:33-45). With the death of her King, unfaithful Israel went from being a queen to a widow (cf. Rev. 18:7-8).And I will bring a sword against you that will execute the vengeance of the covenant . . . I will bring the land to desolation, and your enemies who dwell in it shall be astonished at it. I will scatter you among the nations and draw out a sword after you; your land shall be desolate and your cities waste.
Leviticus 26:25, 32-33; cf. Deuteronomy 32:28-43; Matthew 23:32-36
DOES “ALL THINGS” MEAN EVERYTHING IN THE BIBLE?
In evaluating what the “all things’ in Luke 21:22 refers to, it is useful to look at other sections of Luke that have similar references to “all things.” Consider Luke 18:31:
In Luke 18:31 Jesus tells his disciples that "all things" written about him by the prophets would be accomplished at Jerusalem. If one uses the logic that full preterists use on Luke 21:22, one would say that all the prophets said about Jesus was fulfilled at Jesus’ crucifixion in AD 30. This, of course, is not correct; to use such logic would be making a serious error. One would end up trying to fit the AD 70 coming of God to defeat the Antichrist (Dan. 7:21-22)—what the NT reveals as the parousia of Jesus (Rev. 19:11-21)—in with, or before, the crucifixion. What Luke 18:31 is saying is that all that was written about Jesus’ suffering, dying, and rising in victory on the third day would be fulfilled in his death and resurrection at Jerusalem. All the specifics written about these events would be fulfilled at that time, not all things written about Jesus by the prophets.Then He took the twelve aside and said to them, Behold we are going up to Jerusalem, and all things which are written through the prophets about the Son of Man will be accomplished.
Luke 18:31
Another Lukan “all things” statement was made by Jesus after his resurrection.
Once again, this did not mean that all the prophecies in the Law, Prophets, and Psalms (i.e., all the prophecies in the Bible) about Jesus were fulfilled by the time of his resurrection. Few, if any, would deny that Jesus’ Second Advent and full kingdom reign still awaited a post-AD 30 fulfillment (cf. Matt. 16:27-28; Luke 19:11-27). What Jesus meant by “all things” was that everything that happened at Jerusalem had to happen to fulfill all the prophecies about him dying and rising again. This is made clear as Jesus continues in chapter 24:Then He said to them, “These are the words which I spoke to you while I was still with you that all things must be fulfilled, which were written in the Law of Moses and the Prophets and the Psalms concerning Me.”
Luke 24:44
To summarize: taking into consideration Luke’s similar uses of “all things” (e.g., Luke 18:31; 24:44), Luke 21:22 is saying that all things that were written in the Old Testament about the days of vengeance on unfaithful Israel would be fulfilled by AD 70 with the destruction of Jerusalem. To say the "all things" of Luke 21:22 means that all the prophecies in the Bible were to be fulfilled by AD 70 is unwarranted. When one looks at Luke's use of "all things" they speak of all the specifics of a given prophetic event being fulfilled, not all the prophecies in the Bible being fulfilled.And He opened their understanding, that they might comprehend the Scriptures. Then He said to them, “Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem. And you are witnesses of these things.”
