This article is to present the key requirements for the successful Christian counseling by considering Job in the perspective of Habermas’s theory of communicative action. A psychic counseling, whether directive or non–directive, has concentrated it’s effort on solving client’s problems. In this respect, a psychic counselor has generally pursued an instrumental rationality for solving a client’s problem and has selected and developed the various techniques of counseling in the view of instrumental rationality. But, in Christian counseling, a counselor is not a trouble–solving broker to solve client’s problems, but an assister to assist his client to get near to God and to listen to His words. Thus, a counselor must adhere to communicative rationality, as mentioned by Habermas, in the process of counseling for his successful assistance. In a word, Christian counseling is to lead a client to truth, and make the Word of God, “the truth will set you free”(John 8:32), come true.
