But if you have bitter jealousy and selfishness in your hearts, do not boast and tell lies against the truth. Such wisdom does not come from above but is earthly, natural, demonic. For where there is jealousy and selfishness, there is disorder and every evil practice. But the wisdom from above is first pure, then peaceable, gentle, accommodating, full of mercy and good fruit, impartial, and not hypocritical. And the fruit that consists of righteousness is planted in peace among those who make peace.
It is important that we be mindful of the things that come out of our mouths. For even if it is through our mouths that we are able to deliver God's words and be able to praise His holy name, it is also through our mouths that we are able to bring the greatest of destruction. So let us cleanse our hearts so that our wisdom may come from above and that we may speak only what God wants us to speak.
