Adrian Warnock has some very useful reflections on the pressures pastors face and how hard they find the job, especially the isolation. His figures come from the USA, but a very similar picture could be painted here, as we know from the Pastoral Refreshment Conference.
Adrian finishes with a call to encourage your pastors. I wholeheartedly agree. (send them and their spouses on the Pastoral Refreshment Conference as a gift!)
