How is the word made effectual to salvation?

The Spirit of God makes the reading, but especially the preaching of the word, an effectual means of enlightening,^[1] convincing, and humbling sinners;^[2] of driving them out of themselves, and drawing them unto Christ;^[3] of conforming them to his image,^[4] and subduing them to his will;^[5] of strengthening them against temptations and corruptions;^[6] of building them up in grace,^[7] and establishing their hearts in holiness and comfort through faith unto salvation.^[8]
