I have found that reading Ironside on biblical subjects is a rewarding thing (we are all familiar with his commentaries). Ironside was converted in the Holiness movement of the Salvation Army. He quickly became a student and then a teacher in the movement. He retained the zeal found there the rest of his life. The one doctrine that he could not square with Scripture was that of the attainment of sinless perfection. This book is the result of his study and consequent refutation of that doctrine. Ironside does his usual thorough job with the subject matter and adds his passion for true biblical holiness. The reader will find solid application of the believer’s position in Christ related to his sin and his progressive sanctification, resisting equal errors of sinless perfection on the one hand, and antinomian license on the other.
