Regarding your question about faith in devotees, faith must be there. But we should always take instruction from devotees who are considered to be elevated. A preacher's position is like this: He should have firm faith and love for Krishna. He should make friendship with devotees. He should be very much charitable and kind to the neophytes and he should avoid the company of nondevotees.
