Both Jesus and the Apostle Paul modeled accessibility and had close bonds with their disciples. That's the way we should do ministry.
A friend in Alabama recently told me about a preacher who came to his city in unusual style. The man arrived at a church in a limousine and was whisked into a private waiting room behind the stage area. The evangelist gave specific instructions to leave his limousine's engine running (I guess he wasn't concerned about rising gas prices) so that the temperature inside his car would remain constant.
This evangelist then preached to a waiting crowd, took up his own offering and retired to the waiting room for some refreshments. Then he left the church with his entourage without even speaking to the host pastor.
