Hebrews as Hermeneutics, and Apologetics.

Hebrews 8:13 (ESV)
In speaking of a new covenant, he makes the first one obsolete. And what is becoming obsolete and growing old is ready to vanish away.

“In speaking of a new covenant, he makes the first one obsolete.” It is sort of funny. We think of Christ as making the old one obsolete. But the writer of Hebrews, draws attention to the fact, that even God speaking of a New Covenant, has told the people this one isn’t working. This is an instance where the Gospel is revealed even in the Old Testament. God is showing the people that the only thing that will work is the forgiveness of sins. In a manner of speaking than, this speaking of the New Testament, has drawn it up, Jesus Christ, doesn’t establish it of himself alone, but he consummates it with his death.
The more I read Hebrews, the more I see it as a great hermeneutical text for the Old Testament. Not only does it proclaim the gospel loud and clear itself by citing the Old Testament, it gives us the rules, and examples of how we too should read the Old Testament. I suppose this is what is meant a bit by Scripture interprets Scripture. That is Scripture itself tells you, if you bother to read it, and care to find out, how you should interpret Scripture. However Hebrews also provides one with the best apologetic for dealing with faithful Jews. It shows you how to read their own books, and use books they agree are from God himself, to explain to them the necessity of Christ. You can use it with others to show how the ceremonial, and state laws of the Old Testament no longer need to be adhered to, and the moral law of the old testament, should only be adhered to out of love for your neighbor, as it does nothing for your salvation.
