38.What is Paul’s conclusion?

The Law of Moses, that which the Judaizers were attempting to add to the Gospel of Christ, corresponds to the bondmaid, Hagar. The Gospel of Christ corresponds to the free woman, Sarah. The Law of Moses "shall not be heir" along with Christ.

We who are Christians are of Sarah, not of Hagar. Therefore we are free. We are not to attempt to add to our freedom in Christ the bondage of the works of the Law of Moses.
