The mouth and using wisdom

I have many thoughts in my head and I like to talk. This is a bad combination because I say my thoughts. My thoughts are sometimes not good. We need to use wisdom when we speak to other people.
Many people will get be in trouble because the word usage. They need self-control in their lives.
A person can lose their job, a relationship and cause war when words are spoken in moment of insanity.
If this apply to your life then you need a new heart.
God loves people and want the best for everyone. When a person accepts Jesus, then there is new life.
The heart speaks what the person thinks.
When I follow the Lord, then my word usage is good. But when I refuse to follow Jesus, then I will say something stupid. If  I say something stupid then I will receive some trouble. This because of my mouth and not my faith in Jesus.
I think that we need to examine our hearts. We need to ask the Lord to change our hearts. Then our words will be nice and not evil.

Proverbs 13:3

Those who guard their lips preserve their lives,
    but those who speak rashly will come to ruin.
