What does the Bible say about profiting from the word of God?

In Hebrews 4:2, we see that the gospel was preached to both the Israelites and us, yet it did not benefit them because it was not mixed with faith. This highlights the essential role of faith in receiving the Word of God. Scripture repeatedly emphasizes that hearing the gospel is not enough; it must be accompanied by a heart that believes and acts on that faith. The children of Israel had the promise of entering God's rest, but their lack of faith prevented them from profiting from the word preached. Thus, the vital takeaway is that without faith, the gospel will not produce the rest and salvation it is meant to provide for believers.
