As I look back over the giants of faith, all had one thing in common: neither victory nor success (in their prayer life), but passion. An emphasis on spiritual technique may well lead us away from the passionate relationship that God values above all. More than a doctrinal system, more than a mystical experience, the Bible emphasizes a relationship with a Person, and personal relationships are never steady-state.
