Preterist after Preterist focus on the year 70ad when old things pass away and new things begin. Again, this places ALL in the new covenant, or the new heavens and earth. If the present heavens and earth which are reserved for judgment of the ungodly, and those outside of Christ, how can it ever pass away while this world remains. Are Preterist saying they are are worthy to enter the new heavens and earth where only the righteous dwell. (2 Pet 3:13) Are they saying the ungodly are also in the New Jerusalem which is the ONLY thing pictured in the New Heavens and Earth in Rev. 20? How can this be? All old things must continue to remain as symbols of those outside Christ.
David Curtis Article: Heaven & Earth and the Law Have Passed Away
Isaiah 65:17 (NKJV) "For behold, I create new heavens and a new earth; And the former shall not be remembered or come to mind. This prophecy had to be fulfilled before the law could pass away. Until God created a new heaven and earth, the old covenant remained in tack, every bit of it. So, if we are not living in the New Heaven and Earth today, then we are under the law, every bit of it. But I know of no Christian who would say that ALL the Old Testament Scriptures are binding on us. If they did, they would have to be keeping the Sabbath, and the feasts, and they would have to be sacrificing animals. Are we bound by the Old Covenant Law today? No! Hopefully, we learned in our last study that we are not under the law. And if we are not under the law, then heaven and earth must have passed away.
He goes on to say this: "According to Matthew 5:17, 18, the Law and the Prophets (the whole Old Testament) have their place under the administration of Christ under the New Covenant." Is that true? NO! The Old Covenant has NO place in the New Covenant! Why is that so hard to understand? The New Covenant replaced the Old. And believers today live under the New, not the Old Covenant. (If the Old Covenant has no place in the new covenant, then the ungodly have no place in the new heavens and earth, or in the age to come.)
