[quoting Jesus] “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.”
Seems clear enough to me. This connects to the same idea about legacy that I wrote about earlier this month. Give it a read.
