Why is preaching God's word important?

Preaching is essential in the Reformed perspective as it is the primary means by which God communicates His grace and calls sinners to Himself. Ezekiel was commanded to 'prophesy to these bones,' which illustrates the power of God's word to bring life to the spiritually dead. In Romans 10:17, we learn that faith comes by hearing, and hearing by the word of God. This underscores how vital it is to declare God's sovereignty and truth, leading to repentance and faith. Preaching should not be focused on entertainment or self-help but rather on the gospel's power to save sinners.
