The sermon contrasts Naaman, the proud Syrian commander who is humbled and healed through faith in God's appointed means, with Gehazi, Elisha's servant who, despite witnessing miraculous works, is consumed by greed and loses his spiritual inheritance. Central to the message is the truth that salvation comes not through human merit or religious privilege, but through humble obedience to God's Word and faith in Christ alone, illustrated by Naaman's cleansing in the Jordan and the raising of the dead child—a foreshadowing of Christ's resurrection. The preacher emphasizes that while Naaman, though ignorant of Israel's faith, acknowledges Jehovah as the only true God, Gehazi, despite his intimate knowledge, worships the god of money, revealing that true faith is not measured by knowledge but by heart posture. The sermon warns against using Naaman's actions to justify participation in idolatry today, arguing that God no longer tolerates such practices, unlike in the Old Testament era, and calls believers to repentance and exclusive trust in Christ, the only true Savior, whose resurrection is the ultimate sign of God's power and grace.
