I've just listened to a sermon on Servant Leadership delivered by Dr Dan McCartney at chapel at WTS. Many thanks to Jonathan Kirk, my brother, and Daniel Kirk at Sibboleth for pointing me to it. As Daniel says 'it's a must-listen' if you're in leadership yourself. If that's not enough to grab you for the whole 22 minutes of the sermon, then listen from 19:30 in and you get a good 2 minutes that's a powerful conclusion to the message. Find it here.
