Ephesians 4: 29
Let no corrupt communication proceed out of your mouth, but that which is good and to the use of edifying, that it may minister grace unto the hearers.
Proverbs, 15:4 (amp)
A gentle tongue ( with its healing power) is a tree of life, but willful contrariness in it breaks down the spirit
Luke 6:38
Give,and it shall be given unto you;good measure, pressed down, and shaken together, and running over, shall a men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again.
(12) Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. (13) For it is God which worketh in you both to will and to do of his good pleasure.
Proverbs 28:25
He who is of a proud heart stirs up strife, but he who trusts in the LORD will be prospered." God resists the proud, but gives grace (gifts that prosper one spiritually) to the humble.
