Why is the preaching of the gospel essential for faith?

Romans 10:14-17 illustrates the necessity of preaching for the establishment of faith. It asserts that individuals cannot call on the name of the Lord unless they believe, and they cannot believe unless they hear the gospel. The faithful proclamation of the Word reveals Christ, convicts of sin, and lights the path for those who are lost. This vital process underscores that the means through which the Holy Spirit works in the hearts of the elect to bring them to saving faith is through the faithful preaching of the gospel.
