Darrell Harrison delivers a penetrating exposition on the Hypocrisy of the Heart, examining Jeremiah 17:9's declaration that "the heart is more deceitful than all else and is desperately sick." This profound message confronts the reality of indwelling sin that remains even in regenerate believers, dismantles the false doctrine of sinless perfection popularized by Charles Finney, and exposes the frailty of our unredeemed flesh.

Harrison challenges the contemporary evangelical assumption that salvation renders believers incapable of sin, instead demonstrating through Scripture and Puritan wisdom that progressive sanctification—not sinless perfection—marks authentic Christian life. This message reveals how our deceitful hearts pursue truce with sin rather than relying on the Holy Spirit's transforming power.
