Many pressures and demands pull on the pastor’s time. A full-time capacity does not allow enough time to address them all, though I wish it did. Be wise and diligent with whatever time you are given, and delegate to other capable servants in the church so you are able to focus on that which God calls us to whether bi-vocational or full-time.
