Oh, so NOT true necessarily. I'm sure it's the case sometime, but not always. I know of a very Biblically sound pastor in our area who has a great ministry and growing church - mostly new Christians or those who are curious seekers - and he is "cool" - but does not pander to the "seeker sensitive" crud and does not compromise on the Word at all.
There is a great pastor like that in Asheville. Sticks to God’s word and God’s love. Their church is really growing.
