If we win souls, we will be wise  -  Proverbs 11:30

The fruit of the righteous is a tree of life; and he that winneth souls is wise.

 A righteous life is like a fruit-bearing tree that brings nourishment and refreshment to others and the individual that is wise, will win others to that life of wisdom and righteousness. It is a privilege to be used of God to do a work in a human life that will result in eternal blessing.
