Here is an extended quote from the message this morning on Mark 6:1-6.
“We can never be too much on our guard against unbelief. It is the oldest sin in the world. It began in the Garden of Eden, when Eve listened to the devil’s promises instead of believing God’s words, “you will die.” It is the most ruinous of all sins in its consequences. It brought death into the world. It kept Israel out of Canaan for forty years. It is the sin that especially fills hell. “Whoever does not believe will be condemned” (Mark 16:16). It is the most foolish and inconsistent of all sins. It makes people refuse the plainest evidence, shut their eyes against the clearest testimony, and yet believe lies. Worst of all, it is the commonest sin in the world. Thousands are guilty of it on every side. They claim they are Christians…But in practice they are really unbelievers. They do not implicitly believe the Bible and receive Christ as their Saviour. Let us watch our own hearts carefully in the matter of unbelief. The heart, and not the head, is the seat of its mysterious power. It is neither the lack of evidence nor the difficulties of Christian doctrine that make people unbelievers. It is lack of will to believe. They love sin. They are wedded to the world. In this state of mind they never lack specious reasons to confirm their will. The humble, childlike heart is the heart that believes.”
