The Hebrews

Romans 10
8 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;

In this passage, we find that the Hebrews are not saved.

More From 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.

The keys to heaven, for the Jew and the Gentile alike: faith and Christ.  On the other hand, I don't think this is going to be my last word on the Hebrews.
