You know trees by their fruit. Healthy trees make good fruit, and sick trees don’t. Likewise, is it possible to get grapes from thorn bushes or figs from thistles? Be on the watch for false teachers who pretend they are innocent sheep, when really they are dangerous wolves, eager to tear you apart.
What you have stored up in your heart determines what you say. The good man’s speech proves that he has goodness within him. An evil man is filled with poison and his words reflect that. Evil people are as dangerous as a nest of snakes. It isn’t possible for evil people to speak the truth.
When judgment day comes you will have to give account for every word you have spoken. What you say now impacts on your fate then. Either you will be justified by your words or you will be condemned, just like how a tree that doesn’t produces good fruit is cut down and burned.
