How does God demonstrate His power through the preaching of the gospel?

The demonstration of God's power is intricately tied to the faithful preaching of the gospel. In 1 Corinthians 2:4, Paul notes that his preaching was accompanied by a demonstration of the Spirit and power. This indicates that true gospel preaching is not merely a conveyance of information but involves the active work of the Holy Spirit in the hearts of listeners. As the gospel is preached, it has the power to regenerate, convict, and transform, leading to faith as the Spirit of God applies the truth and reveals the glory of Christ. Thus, the effectiveness of preaching rests in the divine power working through it to effectually save the elect.
