Western threapies do not reckonize sin.  In fact, western therapies, of which there are many have no understanding of the religious dimension of persons.  Western therapies are secular systems that are prejudiced against biblical humanism.  The Word of God does not use therapies.  People need the Word of God because it alone has the one message that fully and comprehensively elucidates the human condition.  Jesus is the Theanthropos.  He fully leads out for humans the will of God for our lives.  As those who profess to know God we must reckon ourselves dead to sinful practice.
