Matthew 12:33, 36-37

“Either make the tree good and its fruit good, or make the tree bad and its fruit bad; for the tree is recognized and judged by its fruit.

But I tell you, on the day of judgment people will have to give an accounting for every careless or useless word they speak. For by your words [reflecting your spiritual condition] you will be justified and acquitted of the guilt of sin; and by your words [rejecting Me] you will be condemned and sentenced.”
