The preaching in Christ’s church sets forth the doctrine of the gospel in all its glory and power. It is pure, unmixed with the errors of Pelagius or Arminius that ascribe to man a part in his salvation. It is uncorrupted with Romish or Federal Vision errors that require man to perform works that will in some way contribute to his salvation. The opinions and philosophies of men are excluded. It must be the pure doctrine of the gospel.
Preaching the pure doctrine of the gospel is the chief mark of the true church of Christ. Every sermon, whether it is expounding prophecy, a psalm, an epistle, or biblical history, is the preaching of the gospel. Sermons on Genesis 1 (creation), Exodus 20 (the law), Haggai 1 (God’s rebuke of Israel), or Matthew 3 (the life of Jesus) must set forth the truth of the text in the light of Christ crucified—the gospel.
