What does the Bible mean when it calls God both just and the justifier? Moreover, was the atonement really necessary? Were there any other ways? In this sermon on the atonement, Dr. Martyn Lloyd-Jones explores these questions in his ongoing series of the Doctrine of the Atonement. After he reviews his previous seven arguments for the Protestant view of the atonement, he gives his final and last reason: the Bible emphasizes the death on the cross as an absolute necessity. By exploring Jesus’s words in the Garden of Gethsemane and epistles of Paul, Dr. Lloyd-Jones gives a clear picture for the biblical and Protestant view of the atonement. Dr. Lloyd-Jones also navigates through some objections against both the general doctrine of the atonement and the specific doctrine of the penal substitutionary atonement. This sermon by Dr. Lloyd-Jones is helpful as he gives arguments for and against this glorious doctrine of the atonement and offers robust understanding of salvation and justification by Christ alone.
