Take every thought captive

An incredibly liberating / healing truth, that Christians can find joy in, comes from 2Corinthians2:5, which implies that initially, thoughts & feelings are 100% totally & completely meaningless, 'until' a conscious effort is made to evaluate them (hold them captive) for truthfulness, using some standard as a guide (Christians use scripture/biblical truth).  In time, living/practicing this truth, will bring healing to Christians suffering from physical, mental, or spiritual illness, caused by chronic negative emotions (ex. fear, envy, worry, anger, or guilt) that have had 'free reign / gone un-confronted'.
