How does the preaching of the gospel relate to salvation?

The preaching of the gospel is essential in the application of salvation, as illustrated in Romans 10:14-15. God has ordained the preaching of His Word as the primary means through which the Holy Spirit calls His elect to faith in Christ. This is not merely an act of persuasion but a divine calling that brings the truth of Christ into the hearts of listeners. As Paul proclaimed in 1 Corinthians 1:21, through the foolishness of preaching, God has chosen to reveal His power and wisdom. The preaching of the gospel guides the hearts of believers towards an understanding of Christ and the assurance of their salvation, emphasizing the necessity of faithful proclamation as part of God’s redemptive plan.
