What does the Bible teach about preaching?

In Luke 4:43, Jesus declares, 'I must preach the kingdom of God to other cities also,' reflecting the centrality of preaching in His mission. Ryle underlines that preaching is not merely a secondary practice but a primary means through which God communicates His truth to humanity. Throughout Scripture, preaching serves as an instrument of divine calling and edification. The church's health is directly linked to the quality and faithfulness of its preaching, making it a crucial element in the Christian faith and life.
