Righteousness = Purity of heart and right living. Righteousness is the result of Justification. Justification = a judicial act of God by which He pardons ALL the sins of those who believe in Christ resulting in acceptance and right standing with the law, i.e. we are conformed to all its demands. Thus we are declared to be entitled to all the advantages, rewards and privileges arising from obedience to the law.
Righteousness is IN Christ through faith.
We put on the the breastplate by: Faith; Hearing/studying the Word; Works/Doing and not believing the lie that we need to fulfil the law to be righteous (Galatians).
