Godly Prayer and Its Answers by John Brown of Wamphray and published by Soli Deo Gloria Publications.
Godly Prayer and Its Answers is an extended meditation upon Christ’s promise in John 14:13–14, “And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask any thing in my name, I will do it.” However, in the process of touching upon everything stated and implied in the text, Brown produces a full and complete treatment of the doctrine of prayer in a manner calculated to promote the exercise of faith in Jesus Christ.
