Wisdom from above vs earthly wisdom

James 3:13-18
[13]Are there people among you who are wise and understanding? They are to prove it by their good lives, by their good deeds performed with humility and wisdom.
[14]But if in your heart you are jealous, bitter, and selfish, don’t sin against the truth by boasting of your wisdom.
[15]Such wisdom does not come down from heaven; it belongs to the world, it is unspiritual and demonic.
[16]Where there is jealousy and selfishness, there is also disorder and every kind of evil.
[17]But the wisdom from above is pure first of all; it is also peaceful, gentle, and friendly; it is full of compassion and produces a harvest of good deeds; it is free from prejudice and hypocrisy.
[18]And goodness is the harvest that is produced from the seeds the peacemakers plant in peace.
