Genesis 6:8-10
   But Noah found favor in the eyes of the Lord.
   This is the account of Noah and his family. Noah was a righteous man, blameless among the people of his time, and he walked faithfully with God.
10  Noah had three sons: Shem, Ham and Japheth.

Noah lived a righteous life and walked with God because he ‘found grace in the eyes of the Lord.’

Grace - meaning

The word “grace” appears for the first time in the Bible in this verse.
"Grace" is the English translation of the Greek χάρις (charis) meaning "that which brings delight, joy, happiness, or good fortune."
The Old Testament use of the word (Hebrew word חֵ֖ן (ẖen) as found in Genesis 6:8) includes the concept that those showing favor do gracious deeds, or acts of grace, such as being kind to the poor and showing generosity.

Grace is not a commodity or a substance. It is an action of God; therefore, it has a result.
