"We define Christian spiritual direction as help given by one Christian to another which enables that person to pay attention to God’s personal communication to him or her, to respond to this personally communicating God, to grow in intimacy with this God, and to live out the consequences of the relationship."
Barry and Connelly's good definition reminds me of a description I once read of the ministry of the Old Testament Prophet, where the purpose of the prophet was to recapture the imagination of God's People back to Him. Christian leaders get the attention of those that follow and lead them back into the presence of God.
