It’s no secret that healthy environments attract healthy people. Healthy people leave environments that are not or more often than not, get pulled down by them. Yet, it is something we tend to forget. When we find a system or environment that is wrong, there is something wrong at the top. It is from there that the change must come if something is out of kilter." [secular source: http://www.leadershipnow.com/leadingblog/index.html]
When it comes to churches, leaders not only determine what sorts of people are attracted to the church, but also in which direction believers mature. Spiritually and relationally healthy leaders attract people who are comfortable with a healthy, balance, Biblical Christianity -- and they also develop disciples in that image. So leadership is crucial.
