When I was a volunteer firefighter our bushfire brigade would respond enthusiastically to fire calls at all times of the day or night. I remember one chilly winter night being called to a house fire to assist the professional fire brigade. The house was empty and it was beyond saving so they left it to us to put it out and keep it from spreading. We all felt pretty good about what we’d done, even though most of us had lost a night’s sleep and still had to go to work at daybreak. We felt envious of the professional firefighters who got to do this for a living, and were surprised to hear them complaining about having been called out. It made me realize that there’s something about being a volunteer that we often lose when we get paid – fun; doing something for the love of it. That’s why true faith is always voluntary.
