What does the Bible say about faith in preaching?

According to Scripture, the effectiveness of preaching hinges not merely on the eloquence of the preacher but on the presence of faith in the listeners. Hebrews 4:2 notes that while the gospel was preached to the Israelites, it was of no advantage to them because it was not mixed with faith. Therefore, faith is a crucial element that God must grant for individuals to truly believe and benefit from His word. This underscores the sovereign role of God in enabling faith, independent of human effort or persuasion.
