How do preachers spread the gospel according to the Bible?

The Bible articulates that the preaching of the gospel is ordained by God to call out His elect from every nation. Romans 10:14-15 outlines the sequence of belief: one must hear the gospel, and to hear, there must be a preacher sent by God. This emphasizes the importance of faithful preaching as a means through which God works to deliver His messages of grace. Preachers are called to proclaim Christ's work, ensuring that their messages affirm God's sovereignty in both creation and salvation.
