Righteousness is Obedience to God's Law

And if we are careful to observe every one of these commandments before the LORD our God, as He has commanded us, then that will be our righteousness.”

For concerning the righteousness that is by the law, Moses writes: “The man who does these things will live by them.”

Both of them were righteous in the sight of God, walking blamelessly in all the commandments and decrees of the Lord.

But his delight is in the Law of the LORD, and on His law he meditates day and night.
