(2.) Metanoeo, meaning to change one's mind and purpose, as the result of after knowledge.

The true penitent is conscious of guilt (Mat_27:3).Psa_119:128; Job_42:5, Job_42:6; 2Co_7:10) and turning from it to God; and (4) a persistent endeavour after a holy life in a walking with God in the way of his commandments.Psa_51:4, Psa_51:9), of pollution (Psa_51:5, Psa_51:7, Psa_51:10), and of helplessness (Psa_51:11; Psa_109:21, Psa_109:22).
