For the record I do not think my church is unhealthy but rather the opposite. Its just I am not Arminian, nor IFB. But it would be easier if I was in a Calvinist IFB church. Anyways what is healthy church? I think that Mark Dever has explained it well on what a healthy church is with this book. The Nine Marks Expositional Preaching Biblical Theology A Biblical Understanding of the Good News A Biblical Understanding of Conversion A Biblical Understanding of Evangelism A Biblical Understanding of Church Membership Biblical Church Discipline A Concern for Promoting Christian Discipleship and Growth Biblical Church Leadership Its not that every healthy church will be a 9 Marks church or Calvinist as there are healthy non-Cal churches such as the Moody Church, & Shadow Mountain Community Church. Regarding unhealthy churches these are churches that do not preach the Biblical gospel or the essentials of the faith. For example I received a email reply from a Presbyterian USA Pastor and he said the following. -- Dear John, We teach that Jesus came and died for all people. We do not teach that other faiths will spend an eternity in hell. We do not believe that it is up to us to judge. It is just up to us to love. I hope that answers your questions. Blessings, Pastor xxxx -- That would be an example of a unhealthy church. A church that lacks an understanding of the gospel, and Biblical conversion. There are other examples of a unhealthy church so preaching the Biblical gospel would be the first step. So what say you?
