Food for thought. Is the salvation of the church is experiencing and the glory she will experience fully in the future really the promise of salvation given to Israel? After all God said he would glorify her. If that is the case then the church is essentially jewish and gentiles are ingrafted into it and receive of the promises and fullness of God’s Grace [that said the church is made up of people from all over the world, but I speak here of her roots]. Not all Israel believes in Messiah, but likewise not all that left Egypt made it into the promised land. So the church is Israel under a new and better covenant, and through this covenant there is now a new man. Made of both Jews and gentiles in Christ for as many as join Him in his death are partakers of his grace, suffering and also will partake of rulership and glory. Because Christ is the true seed of Abraham, born of the stock of David. Those who are joined in his death become one flesh in him and died with Him. They are thus partakers of the promises given to Abraham and are his seed through Christ who lives in them all. For we all died and now it is Christ who lives in us. So now through Christ believers both Jew and Gentile are one man, the seed of Abraham in Christ. This status is earned by Grace and not works, further more the promises of the New Covenant place believers in heavenly places with Christ and make them the recepients of all spiritual blessings in the heavenlies.
Simply put, the apostle’s were commisioned by Christ to spread the Gospel. And He said they would sit on thrones judging the 12 tribes of Israel. This is the nature of Israel and the church. The promises given to the ethnic people of Israel still stand also, and God in his timing will fullfill them. Examples include the boundaries of the land from the Euphrates to the brook of Egypt, salvation of the remnant, rebuilding of the Temple when Messiah returns, being the head and not the tale as far as nations go etc. These will all be fulfilled, but through Christ also. So that He is Glorified and the Father Glorified in Him. Let us not forget that the first visitation of Christ was in fulfillment to promises made to the ethnic people of Israel. And all that happened and is happening is all according to the word of God.
