As stated previously, all promises that God made to Abraham were literally fulfilled by the conclusion of the book of Joshua. I also stated that ultimately, the blessing of Abraham’s seed was fulfilled with Christ.
A few folks aren’t satisfied with what I said previously so let me add the following:
In an ultimate sense, Abraham was promised the whole world which is exactly what Christ was given upon his enthronement in heaven. Also, the New Testament is clear that the heirs or descendants of Abraham are not those descended biologically or genetically but those who have faith in Christ.
Lastly, all remaining promises made to national Israel were fulfilled in Christ. There are no unfulfilled biblical promises to Israel that have yet to be fulfilled now or sometime in the future. Claiming that God is not done with Israel invalidates the clear teaching of the New Testament. Such a claim is false. The replacement Theology advocated by Dispensationalists who maintain that the Church replaces the Jews in the current dispensation of the “Church Age” has zero biblical support. Thus, Mike Huckabee, Ted Cruz, Jack Hibbs, Billy Graham, Hal Lindsey, Tim LaHay, and a host of others are wrong when falsely bifurcating Jews and the Church.
The Church is Israel because at its root, it is built upon the believing remnant of First Century Jews. The Church is a continuation of the faithful with the Gentiles added to its numbers. This is the whole point of the Book of Acts which documents this very transition.
In Old Covenant terms, God divorced His unfaithful bride, national Israel, the whore of Babylon where Jesus was crucified. She was executed via fire, the death of the daughter of the high priest. God took for himself a pure bride, the Church and consummated the marriage with her. Like most of the New Testament, the marriage to Christ was completed in the past, is still happening today as more people are added to the number of the Church and will be fulfilled in its final form at some point in the future. This is the clear teaching of the New Testament; especially, the Revelation.
The Sacrament of Holy Communion is a celebration of Christ’s sacrifice and participation in the Marriage Supper of the Lamb. Properly understood, we enter into God’s Throne Room when we partake of the bread and wine in Communion. Sadly, many Christians don’t understand the theology associated with the Sacrament.
By claiming that God has both the Church and the Jews as his chosen people, Dispensationalists are advocating a perverse form of polygamy by saying God has two brides. That is not New Testament theology; thus, it is a false gospel.
