# Question 155: How is the Word made effectual to salvation? | Westminster Larger Catechism

The Spirit of God maketh the reading, but especially the preaching of the Word, an effectual means of enlightening, convincing, and humbling sinners; of driving them out of themselves, and drawing them unto Christ; of conforming them to his image, and subduing them to his will; of strengthening them against temptations and corruptions; of building them up in grace, and establishing their hearts in holiness and comfort through faith unto salvation.
