So, look . . . if you want to rely upon works of the Law to lay claim to the title "child of God," you can't. To be under the Law is to be a slave, and slaves are not sons.
Paul shows that the Law was never intended to save, but that salvation comes only through promise. The Law merely served as an instructor until the coming of the promised Christ.
Paul has a full head of steam and runs into the ground the notion that we receive the Spirit by works instead of by grace. Instead, we are of Abraham, the man of Christ.
