Jesus said, “A good tree does not bear rotten fruit, nor does a rotten tree bear good fruit. For every tree is known by its fruit. For people do not pick figs from thorn bushes, nor do they gather grapes from brambles. A good person out of the store of goodness in his heart produces good, but an evil person out of a store of evil produces evil; for from the fullness of the heart the mouth speaks.”
Luke 6:43-45
Jesus continues to teach that what comes out of us comes from what is inside of us. Good actions come out of good people and evil actions come out of people who are corrupted at their core. Furthermore, what we say is a reflection of our hearts. If we find sarcasm and criticism and negative speech coming out of our mouths, it reveals the need for our hearts to be cleansed and transformed.
Pay attention to the words that come out of your mouth today. What do those words reveal about your heart? Ask God to purify your heart so that better speech comes out of your mouth.
