What does the Bible say about the power of the tongue?

James 3:7-8 illustrates that while humans have succeeded in taming various creatures, they cannot control the tongue, which is inherently prone to bitterness and evil. However, the grace of God is powerful enough to tame the tongue, transforming it from an instrument of sin into a vessel of truth and kindness. When Christ resides in the heart, His grace not only sanctifies the tongue but also replaces pride and hatred with love, enabling the believer to speak in ways that glorify God and edify others.
