How does preaching affect the spiritual growth of believers?

Preaching plays a foundational role in the spiritual growth of believers by regularly pointing them back to Christ and the gospel. As seen in Romans 10:17, faith comes by hearing, and hearing by the word of God, which emphasizes the transformative power of biblical preaching. This consistent exposure to the truths of Scripture encourages believers to rely on Christ, leading to growth in understanding, maturity, and greater assurance in their faith. The gospel proclaimed serves as both nourishment and motivation, reminding believers of their need for Christ and God's provision through Him.
