“It is hoped this simple volume may now be found to be a compact and more useful channel of Scriptural instruction upon this important subject. The views expressed have been carefully weighed in the balance of the Divine Word, and confirmed by much careful experience and observation.

Effectual faith can only come through thorough conviction.”
