Ah yes... the conclusion... :)
Since Israel is Babylon the Great...
You might also just as well say "Since Jesus is Satan..." Which... I would recommend strongly against. :)
...it means that Israel no longer belongs to God...
Time after time throughout the Bible we are told that God's Israel, which will ultimately consist of true Jews (Romans 2:28-29) an innumerable multitude of people from every tongue, tribe, and nation (Revelation 7, 14) ~ this is His true Israel ~ is what He is building and providing salvation for, saving unto Himself, for His glory...
...Jesus declared that the Jews have lost the kingdom of God (Matthew 21:43) and he called them devil's children (John 8:44).
Unbelievers, yes, symbolically "residents" not of true Israel or true Jerusalem, but of Babylon the great, the "worldly city"... all the ones who, as Paul says in Romans 1,
"...although they knew God, they did not honor him as God or give thanks to Him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools, and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things. Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen. For this reason God gave them up to dishonorable passions..."
All this means that dispensationalism must be false and Fulfillment Theology is true. Fulfillment Theology is often called "replacement theology" by dispensationalists. The Bible declares that the true descendants of Abraham, and thus the heirs of the promises, are the Christians (Galatians 3:29), which confirms the Fulfillment Theology.
Well, agreed on dispensationalism, but "replacement theology" assumes that only believers in New Testament times are Christians ~ in Christ ~ which is false. The Bible declares ~ Paul declares, specifically ~ that the true descendants of Abraham (and yes, heirs of the promises) are all those in Christ from the time of Adam, which is to say even the
true Israelites in Old Testament times ~ before Jesus walked the earth, believers in the prophesied Savior/Messiah to come ~ were in Christ and therefore grafted in to the Vine (Jesus, of course) and therefore Christians. This might much more correctly be called "inclusion theology," as, since Jesus came has included Gentile believers. So both dispensationalism and "fulfillment theology" are false. :)
This knowledge was given to me by Jesus Christ. All praise is due to Him.
Well, I agree that all praise and honor is due only to Christ, but I would humbly submit that the "knowledge" you impart ~ at least on this subject ~ is not from Him at all. The evil one counterfeits Jesus in a great number of ways...
Grace and peace to you.
