What are the things that are so true, so deeply held in your own heart and mind and conscience, so much of a conviction that you are willing to pattern your life and, if need be, to die for them?
Your job and mine is not either to sit in judgment or awe on the other hand to become cynical about Christian leaders and Christian work. Your first job is to keep your own heart right with the Lord Jesus.
Training your mind involves, reading, persuading others, doctrine: what you really believe. Exhortation means how we communicate to others. Your beliefs effect your behavior.
