As someone who has spent the last decade training young men and women for Christian service, I have been keen to help them see that the best kinds of ministry are, more often than not, long term and low key. I have tried to prepare them for a marathon, not a short, energetic sprint. In other words, to help them have a lifetime of sustainable sacrifice, rather than an energetic but brief ministry that quickly fades in exhaustion.
