James 3:14-16, 18

But if you have bitter jealousy and selfish ambition in your heart, do not be arrogant and so lie against the truth. This wisdom is not that which comes down from above, but is earthly, natural, demonic. For where jealousy and selfish ambition exist, there is disorder and every evil thing.

And the seed whose fruit is righteousness is sown in peace by those who make peace.
