This image illustrates Luke 6:44. "A good tree can't produce bad fruit, and a bad tree can't produce good fruit. A tree is identified by its fruit. Figs are never gathered from thorn bushes, and grapes are not picked from bramble bushes. A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart. What you say flows from what is in your heart."
