The book is the overflow of a heart under the burden of seeing the marks of the Lordship of Christ in every aspect of Christian service. Service to the Lord or Christian service begins in God and finds its place in God's eternal purpose. It is to be accomplished in the power of the Holy Spirit by men whom God has called to His work. Christian service is to be done according to God's methods and in God's time. Thus defined, the work of God becomes a very serious responsibility. Read this book and either begin to serve the living God satisfactorily or grow in quality and quantity service for Him.
