'...the structure of sin in the human personality is something far more complicated than the isolated acts and thoughts of deliberate disobedience commonly designated by the word. In its biblical definition, sin cannot be limited to isolated instances or patterns of wrongdoing; it is something far more akin to the psychological term complex: an organic network of compulsive attitudes, beliefs and behavior deeply rooted in our alienation from God. Sin originated in the darkening of the human mind and heart as man turned from the truth about God to embrace a lie about him and consequently a whole universe of lies about his creation. Sinful thoughts, words and deeds flow forth from this darkened heart automatically and compulsively, as water from a polluted fountain.'
Richard Lovelace, Dynamics of Spiritual Life, p.88.
