In the church at the moment there is a renewed emphasis on missional growth, both in numbers and in regard to spiritual depth. But resources are few and to evaluate `effectiveness' we see an increasing adoption of scales and measures to test and encourage that growth (for example the Renewal and Reform agenda in the Church of England). Though good and to be welcomed, the challenge for church leaders is to be ambitious for the Kingdom, whilst keeping hold of their souls. This book will examine biblical perspectives on ambition and success, particularly from the point of view of Jesus and the gospels. It will affirm what is praiseworthy in the current emphasis on church growth, whilst challenging the creep of more secular assumptions about what it looks like to be successful.
