Preaching the gospel is essential because it communicates the message of Christ, the only means by which believers are saved.
The centrality of preaching the gospel in salvation is emphasized in Romans 10, where Paul articulates that faith comes by hearing the word of God. This indicates that the gospel is the means through which God’s grace is applied to individuals. It is through the proclamation of Christ's sacrifice and resurrection that the Holy Spirit regenerates the hearts of those who believe, making them receptive to the grace of God. Therefore, the expository preaching of Christ crucified not only brings forth the truth of salvation but also the necessary response of faith from the listener, emphasizing the vital role of preaching in God's redemptive plan.
