I can tell you without question God is sore displeased with a mouth (words) that cause hurt. In fact I believe it is one one of the biggest sins man can do. Hurtful words is something we all have been a victim of and also something that all of us has sinned with. I know many of the biggest things I have had to forgive involved words that hurt. I am including a section on this because the hurt and damage that words can do is extensive and it is extremely important for the health of your soul to watch carefully what you say. This includes talking behind someone’s back as well. Here are some very serious Scriptures on the matter:
4:24 “Put away from thee a froward mouth, and perverse lips put far from thee”
6:2 “Thou art snared with the words of thy mouth, though art taken with the words of thy mouth”
6:12 “A naughty person, a wicked man, walketh with a froward mouth”
8:13 “The fear of the Lord is to hate evil: pride, and arrogancy, and the evil way, and the froward mouth, do I hate”
10:31 “The mouth of the just bringeth forth wisdom: but the froward tongue shall be cut out”
11:9 “An hypocrite with his mouth destroyeth his neighbor: but through knowledge the just shall be delivered”
13:3 “He that keepeth his mouth keepeth his life: but he that openeth wide his lips shall have destruction”
Jesus says in Matthew 15:18 “But those things which proceed out of the mouth come forth from the heart; and they defile the man”.
Ephesians 4:29 “Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.”
There are a LOT more references to the mouth from The Bible. If God has brought you here because He is teaching you to choose your words carefully be grateful although it will not be easy. It is better to deal with these things now. God still loves you. He knows the mouth is a problem for humans or He would not have talked about it so much in The Bible. God Bless.
