More importantly, you should ask, does that minister LIVE what he preaches. Beware of false prophets. They come in many shapes and sizes. Just because a minister proclaims to be of God, does NOT make it so. Remember, Jesus IS our salvation.
Many ministers see themselves as the message, rather than being the messenger.
Some feel if a minister is not preaching from the pulpit then they are not a minister. I want to say that a minister is much more than that, and much less. A minister is like anyone else. They are struggling with Christianity and following the ways of our Lord every day just like everyone else. If one tells you different, run away as fast as you can.
