Living in the midst of a flesh-pleasing "Christianity", the lives of consecrated men of valor ought to be continually laid before our eyes. We are in danger of thinking that our present lukewarmness is and always has been normal!

Beware! The life of David Zeisberger, Moravian missionary to the American Indians, will challenge any open-hearted reader who desires to be "wine poured out" in the service of our LORD. His consistent choosing of the Spirit over the flesh is a rebuke to our cold, formal missionary shows!
