righteousness
Ephesians 6:14
6:14 righteousness. The “breastplate of righteousness,” protecting the heart and lungs which provide life and breath to carry on the fight does not refer to personal righteous behavior (always imperfect at best) but His righteousness, imputed to us and in us (I Corinthians 1:30; II Corinthians 5:21) through faith by grace and thus eternally impregnable.
