In this sermon on Isaiah 1:5–6 titled “Man in Sin,” Dr. Martyn Lloyd-Jones addresses the need to know the cause of humanity’s troubles in order to begin to understand the proper remedy. Ease, deliverance, and happiness are often enemies of a proper diagnosis. He calls the listener to come face to face with the cause of their ills and see the root of the problems that trouble lives today. The true character, nature, and consequences of sin are examined as they affect the whole of life. Humanity is made blind by sin; all have sinned and are under the very same condemnation. The head and heart are affected by this sin – there is not a part of anyone that goes untouched by sin. Learn of the terrible power of sin against correction, teaching, and trials. The exceeding depth of sin is seen in the increased rebellion against what is good and right. Do not be driven into further arrogance in sin and recognize that all need an entire renovation and this is the very thing God offers through His only Son. The power of the devil is greater than that of humanity; God alone can deliver from this power. Receive this salvation and be delivered from the power of sin.
