Jack Miller died several years back. Some of his letters to believers, leaders and missionaries have been published in a posthumous collection called "The Heart of a Servant Leader". It is a brilliant read, short sections, biblically heart-warming and wise. Here are a few section headings to whet your appetite: * Persevering in serving * Persevering through conflict * Encouragement for sinners * Encouragement for sufferers * Motivation for serving - the glory of God * The basics of serving - faith, humility and prayer
