Following a period of great revival, Charles Finney reached a point of physical exhaustion which resulted in his writing a series of articles on various subjects to continue the work of discipleship in the new believers scattered throughout the regions of revival. These practical instructions were published in the Oberlin Evangelist periodical and took the form of letters addressed to specific themes. They now are collected and edited by Pastor L.G. Parkhurst to appear for the first time in book form.

As well as letters concerning sanctification, major themes include Finney's letters:

• To New Christians
• To Ministers
• To Parents
• To Christians
