James 3:13-18…13 Who among you is wise and understanding? Let him show by his good behavior his deeds in the gentleness of wisdom.
The wise demonstrate their wisdom by their actions–good deeds in gentleness. There are two kinds of wisdom: demonic wisdom and  wisdom from God as described in vv.14-17.
14 But if you have bitter jealousy and selfish ambition in your heart, do not be arrogant and so lie against the truth. 15 This wisdom is not that which comes down from above, but is earthly, natural, demonic. 16 For where jealousy and selfish ambition exist, there is disorder and every evil thing.
James named 11 things that a part of demonic wisdom. They result from a self-centered heart. We may say I have been saved, I am a child of God, and I cannot commit these 11 sins. But, the Bible says “The heart is more deceitful than anything else, and incurable—who can understand it?” A and “Guard your heart above all else, for it is the source of life.” B The heart is the root of our desires of life either good or evil. Left unguarded it will deceive you and you will yield to these evil desires. How much time do you spend guarding your heart against the evil desires of your inner sinful nature- the flesh, Satan and the world system?
17 But the wisdom from above is first pure, then peaceable, gentle, reasonable, full of mercy and good fruits, unwavering, without hypocrisy. 18 And the seed whose fruit is righteousness is sown in peace by those who make peace.
V.17 uses 9 terms to describe the wisdom from God whose fruit is righteousness and peace. We desire this fruit and peace in our lives but are we willing, by the grace of God, to seek it with all diligence?
Continually guard your heart and seek the wisdom of God!
