Proverbs 16:23-24 “A wise person’s heart makes his speech wise and it adds persuasiveness to his words. Pleasant words are like a honeycomb, sweet to the soul and healing to the bones.”
If your heart is right with God, you’ll study His Word and want to follow Him. The end result is that your speech will be gracious and persuasive, and provide guidance and joy!
Colossians 4:6 “Let your speech always be gracious, seasoned with salt, so that you may know how you should answer everyone.”
