Have done so. You will ever reject the simplistic statement of the Apostle.......that is your choice.
And one can not discuss the 11th Chapter without first understanding why Paul is saying what he is saying. That also is "context." Look at Chapter 10.
Romans
10
1 .)
Brethren, my heart's desire and prayer to God for Israel is, that they might be saved.
2 .) For I bear them record that they have a zeal of God, but not according to knowledge.
3 .) For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.
4 .) For Christ is the end of the law for righteousness to every one that believeth.
From here one can read "in context" the rest of Chapter 10, and 11.
And to suggest that all the millions of people who have died in "unbelief" - in their sins - from that time until this.......will be "saved" is to make null and void the blood of Christ in my opinion. For it is to justify "all paths lead to heaven" and to deny that God is a "Just God." To say that of all who have died in unbelief/their sins .......... only those of Jewish blood will be "saved" and all others condemned is to also deny that God is a "Just God."
Paul clearly states that they must not "still abide in their unbelief." Those who have died, died in unbelief. To believe that they will STILL be granted eternal life by God is to justify all paths lead to heaven. For if unbelievers can receive eternal life, then there is no reason for believers to remain in the Faith. If those who live after the flesh can receive eternal life, why should any deny self and live for Him?
Paul speaks clearly again and again.
Galatians 3:
23 .) But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
24 .) Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
25 .) But after that faith is come, we are no longer under a schoolmaster.
26 .)
For ye are all the children of God by faith in Christ Jesus.
27 .) For as many of you as have been baptized into Christ have put on Christ.
28 .)
There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
29 .)
And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
Chapter 4:
4 .) But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5 .)
To redeem them that were under the law, that we might receive the adoption of sons.
6 .) And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
7 .)
Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ.
Believe as you wish...........but there is much to be reconciled with the teachings of Paul under your assertion. I will accept the Words of Christ and the teachings of Paul.
