Often churches hire ministers to do those things that the body doesn't have the desire or the talents to do. We see this often in the case of evangelism, youth, or discipleship. I think in the case of desire, it is wrong for a church to hire a minister to do that which a church should already be doing. It will just lead to a minister getting burnt out and a body of believers not growing. The body needs to change and have the desire to the things which the body of Christ should be doing.
In the case of talents, I think the case can be better made to hire a minister. We see this in the case of preaching and music leading. I just wonder if we value those roles too much, and that they aren't as necessary as our church culture has made them out to be.
Watch out for the potholes
