Elders are to preach God’s word and they are to be an example in what they say or don’t say. Be an example by the way you live out your life. We can only show God’s love to others by spending time in God’s presence.
If you work in Christian ministry it is work. As a boss to others don’t boss people around, but lead them. Be gentle when giving criticism. Be courteous.
John Mark left the team of Paul and Barnabas. There are human reasons for quitting, but never for giving up on God. We need to make sure we are in the place where God wants us to be.
