Please meditate on the following verses concerning the words of your mouth...

Proverbs 13:2, 3 "A man shall eat good by the fruit of his mouth: but the soul of the transgressors shall eat violence. He that keepeth his mouth keepeth his life: but he that openeth wide his lips shall have destruction."

Proverbs 16:24 "Pleasant words are as an honeycomb, sweet to the soul, and health to the bones."

Proverbs 18:21 "Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof."

Proverbs 21:23 "Whoso keepeth his mouth and his tongue keepeth his soul from troubles."

We as believers must learn to lean our entire human personality on God in Christ Jesus. This must be done with absolute truth and confidence in His power, wisdom and His goodness.
