At the very start of some new church or ministry, you gotta find leaders. You don't really just want to appoint leaders, or even train leaders, you want to find leaders. These are the ones who are taking the initiative, showing hospitality, turning up early to set up and staying late to pack down. These are the ones who are internalising the vision of the ministry.
You may invest energy in people, for the spiritual growth, in the hope that they will become potential leaders. But it's out of your hands. You teach, you pray and then you wait.
