Matthew 16:21-23

1. We learn from these verses that there may be much spiritual ignorance even in a true disciple of Christ.
2. Let us learn from these verses that there is no doctrine of Scripture so deeply important as the doctrine of Christ's atoning death.

"The error that drew from so loving a Savior such a stern rebuke to such a true disciple, must have been a mighty error indeed...Error on many other points is only a skin disease. Error about Christ's death is a disease at the heart."
