What does the Bible say about the preaching of the Word?

In 1 Corinthians 1:21, it is revealed that God has chosen to save believers through the method of preaching, which may appear foolish to the world. This reflects God's wisdom, as He designed that human wisdom alone would not lead to true knowledge of Him. Instead, preaching serves as the divinely ordained means by which individuals are called to repentance and faith in Christ. It underscores the necessity for a biblical understanding of preaching as vital for salvation, reaffirming that it is through the preached word that God draws His elect to Himself.
