I just finished a book by Steve Lehrer called New Covenant Theology. I was impressed. I found it to be very Biblical and agreeable. I thought I subscribed to Covenant Theology, so I was surprised to read his perspective of Covenant Theology, especially concerning Israel being the believing people of God before Christ.
I am a bit uncomfortable with his treatment of the law for a new covenant believer. He suggests that our law, or the Law of Christ, is simply the sum of all the commands from Jesus or the Apostles recorded in the New Testament. I don't know how or what exactly to refute about this, but it just seems a bit narrow, or cold. I see the apostles reading and using the Mosaic Law for the church, and I want to know how to read Moses the way they do. When Paul quotes God's law concerning muzzling the ox while threshing, he seems to understand that there is more to the law than meets the eye. I'm pretty sure we can learn God's will for the Christian by reading Moses' writings, though we must learn to see beyond the veil. Steve Lehrer often says that we must read the Old Testament through the lens of the New - I agree.
All in all, I was very comfortable with his words. He directly answered many of my longstanding questions concerning the law, Israel, and the Christian - and with much grace and brotherliness. I found it addressed the crucial points of the debate with relative brevity, without getting bogged down with the rhetoric of many theological books. That means it was good for me, who has a hard time finishing books.
