The heart is the center of the spiritual life.
If the fruit of a tree is bad, you don’t try to fix the fruit; you treat the roots.
And if a person’s actions are evil, it’s not enough to change habits; you have to go deeper.
You have to go to the heart of the problem, which is the problem of the heart.
Above all else, guard your heart. Proverbs 4:23
From The Applause of Heaven by Max Lucado
