That promise is the subject of this book. After offering a collection of pertinent biblical passages, Ellen G. White sets forth conditions for answered prayer and explains why God does not always say Yes to every request for healing.

She also discusses the preparation necessary on the part of those who pray, the importance of submitting to God's will, and the relationship between miraculous healing and physical remedies. The book includes an illuminating case history in which God revealed why He declined to answer a prayer for healing.
