Evangelical counseling ought to use not psychological technique but means of grace. Holy Spirit has to be foundation of Christian counseling. Ultimate purpose of Christian counseling is to be effective change of a client. Counseling without Holy Spirit is not useful counseling for a church. Secular counseling was based on the psychotherapy that ignores work of Holy Spirit. Accordingly, Christian counseling does not accept secular psychotherapy totally.
