James 3:14-16, 18

But if you have bitter jealousy and selfish ambition in your hearts, do not be arrogant, and [as a result] be in defiance of the truth. This [superficial] wisdom is not that which comes down from above, but is earthly (secular), natural (unspiritual), even demonic. For where jealousy and selfish ambition exist, there is disorder [unrest, rebellion] and every evil thing and morally degrading practice.

And the seed whose fruit is righteousness (spiritual maturity) is sown in peace by those who make peace [by actively encouraging goodwill between individuals].
