How do we know that preaching is the means of God’s truth?

1 Corinthians 1:21 states that it pleased God by the foolishness of preaching to save those who believe. This underscores that God's primary method of communication is through preaching, not through human wisdom or elaborate philosophies. Preaching serves as a divinely ordained means to provide knowledge of God and His salvation. The faithful preacher, appointed by God, delivers the gospel truth that has the power to save, unearthing the spiritual need within people for divine direction and understanding.
