These people have the greatest need to know their leaders outside of the church meeting environment. Even if persons are not seeking to be leaders, but are given significant roles of visibility or influence in the church, they are usually also held to a similar standard expected for leadership. This is because anyone who stands in front of people performs a role of leadership whether they intend to or not. In times past, I've known some in the church to be extremely gifted as musicians, singers, or teachers who could have been a great blessing to the fellowship, but they showed such immaturity, unfaithfulness, or impure character, that I could not use them, as it would put them forth to the congregation as an example. Gifts and talents are obviously important, but sincerity and integrity is far more critical than how talented they are.
Leaders lead by example.
And of course, what they stand in front of is people. A leader stands in front of people in order to be seen, because a leader is one who demonstrates a visual example. A leader is a role model who leads the way, who shows how it's done. Leaders must be good followers in order to be good role models. Usually a pastor will not have a problem encouraging the congregation to do what he's been able to get his leaders to do.
