What does the Bible say about controlling the tongue?

James 3:2 emphasizes that if one can control their speech, they demonstrate spiritual maturity. The tongue, though small, can create significant impacts, both positive and negative. It highlights the importance of being slow to speak and considering our words, as every believer, including teachers, has the potential to offend through their speech. The grace of God is offered to help believers tame their tongues for the glory of God and the benefit of the church, acknowledging that while humans struggle to control their tongues, God's power can enable such change.
