A well of life

"Let's open our bibles to the book of Proverbs 10:11" said the preacher.
Proverbs 10:11- The mouth of the righteous is a well of life, but violence covers the mouth of the wicked.
I was really puzzled, how can the mouth of man be a well, not an ordinary well but a well of life? So I began my quest. ........

A righteous man is a man who has a right standing with God. He is morally good and follows the laws of God. There's another special thing about the lips of the righteous :
Proverbs 10:31-32- The mouth of the righteous brings forth wisdom but the perverse tongue will be cut off. So wisdom is the well of life and this proceeds from the lips of the righteous.

We talked about the lips of the righteous, there are still more attached to the righteous
Proverbs 11:10- When it goes well with the righteous, the city rejoices. And when the wicked perishes, there is jubilation.
Proverbs 11:28- He who trusts in his riches will fall, but the righteous will flourish like a foliage 
Proverbs 15:6- In the house of the righteous, there is much treasure, But in the revenue of the wicked is trouble .

You can see all the goodies attached to the righteous. How can one be righteous? ?
Receiving Jesus, the righteousness of God
Being blameless :Proverbs 13:6- Righteousness guards Him whose way is blameless. ....
