What does the Bible say about the power of preaching?

The Apostle Paul emphasizes in 1 Corinthians 1:18 that the preaching of the cross is not merely a message but the very power of God for salvation. This reflects the sovereignty of God in choosing what the world considers foolish—the message of the cross—to confound the wise. When preaching is done in the Spirit, it glorifies Christ and demonstrates the true power inherent in the gospel, enabling sinners to come to faith. The preaching of the gospel serves as a means ordained by God to call out His elect and reveal the truth of salvation through Christ's sacrifice.
