The tongue of the people

The words of the people express the heart. The words can be wise or foolish.
There are times when I am foolish and my words are evil.
I can say many evil ideas that teach people that I am a fool.
Then I need to repent from my sins and follow Jesus.
If I follow Jesus then I will read the Bible. When I read the Bible and apply the Bible in my heart.
Then my heart will be wise because God is changing my heart for the better.

Proverbs 15:2

 The tongue of the wise adorns knowledge,
    but the mouth of the fool gushes folly.
