Righteousness

Therefore, righteousness denotes the fulfilled expectations in relationships between man and wife, parents and children, fellow citizens, employer and employee, merchant and customers, ruler and citizens, and God and man

For example, Adam and Eve would have acted righteously in their relationship with God if they had obeyed Him, because His commands defined that relationship. The Ten Commandments and related laws defined Israel’s relationship with God. To obey those laws was to act righteously, because such obedience maintained the covenant relationship between God and His people.

Righteousness. God the Father is righteous (just); Jesus Christ his Son is the Righteous (Just) One; the Father through the Son and in the Spirit gives the gift of righteousness (justice) to repentant sinners for salvation; such believing sinners are declared righteous (just) by the Father through the Son, are made righteous (just) by the Holy Spirit working in them, and will be wholly righteous (just) in the age to come. They are and will be righteous because they are in a covenant relation with the living God, who is the God of all grace and mercy and who will bring to completion what he has begun in them by declaring them righteous for Christ’s sake.
