The perspective the Scriptures teach us to have concerning all things is and absolutely true perspective. Non-absolute true statements can still exist in the scriptures which can contradict each other, and yet still both be true. Absolutely true statements cannot contradict one another and both be true. The Bible does not contain contradictory absolute statements which are both true.
The grace body of doctrine in the revelation of the New Testament mysteries is an absolute perspective for us today, and the Law body of doctrine which is a contradictory absolute from the Old Testament does in fact contradict grace. The is abolished, not diminished nor improved by grace. Grace has obliterated the Law and contradicted it away from existence
