We speak words of praise to God, and with the same tongue we curse our fellow man. This ought not to be part of our lives (James 3:9-10 James 3:9-10  Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.
 Out of the same mouth proceeds blessing and cursing. My brothers, these things ought not so to be.

Good advice is to control our tongues by controlling our thoughts. Our words tend to reflect what is in our heart (Matthew 12:34 Matthew 12:34O generation of vipers, how can you, being evil, speak good things? for out of the abundance of the heart the mouth speaks.

Somehow we will express what we are thinking—maybe in confidence, but words fly quickly. When we examine the way we think and how we control that, we will never have to worry about a strange “bird” carrying our thoughts where we would not want them to go (Ecclesiastes 10:20 Ecclesiastes 10:20Curse not the king, no not in your thought; and curse not the rich in your bedchamber: for a bird of the air shall carry the voice, and that which has wings shall tell the matter.
