W. E. Best is a Baptist pastor and an excellent teacher of the Bible. The author chose this title (not to sin) to describe the Christ because it expresses the divine truth that Christ could not sin for the reason that as God He was perfectly holy, and as man He was perfectly holy. "Holiness is far more than the absence of sin; it is positive virtue. The Lord Jesus could not sin because the days of His flesh meant only addition of experience, not variation of character. Holy humanity was united to Holy Deity in one indivisible Person, the impeccable Christ." It could not be otherwise, else, the holy Deity would have been defiled by any unholiness in the human flesh. This book slays completely Satan's lie which says that Christ was human, therefore, He "could have sinned, but did not." Yes, He was "tempted (tried) in all respects according to our likeness, apart from sin." However, the trial, or test, was to demonstrate His perfect holiness, that regardless of stress or trial, it was impossible for Him to sin. In short but powerful sentences, the author comprehends the mysterious and marvelous Person who is the Christ. He covers such pregnant subjects as The Eternal Son of God; The Son Declares the Father; The Mystery of Godliness; The Incarnation; the Virgin Birth; Christ's Human Nature; Christ's Human Soul; Christ's Human Growth; Christ's Baptism; Christ's Temptation; Christ's Impeccable Life; The God-approved Man; Christ's Prayer Life; The Drawing Power of Christ; Christ's Discriminating Message; Christ's Miracles; Christ's Death; Christ's Headship; and, Christ's Kingship.
