If your speaking words that are damaging to yourself or others, cancel them in the name of Jesus. That keeps the enemy from launching an attack that will be affective against you, or them. Putting pressure on the bit changes the horses direction, pulling back on the reigns, he adjusts his course. Putting pressure on your tongue by pulling back on the reigns of “derogatory speech” and replacing it with the word of God, changes life’s direction.
James 1:26
If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man’s religion is vain.
