For where jealousy and selfish ambition exist, there will be disorder and every vile practice. But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere. And a harvest of righteousness is sown in peace by those who make peace (James 3:16-17).
By nature we are jealous and self-centered. This is the explanation for our disordered world that is filled with every vile practice.
When people are self-focused, obstacles to their personal happiness must be removed. Once the mirror reveals that there is someone more beautiful--then apples must be injected with poison. The poision may be of the sort that takes the breath, causes a deep sleep or breaks the heart.
Bitter jealousy and selfish ambition produce a harvest of unrighteousness. Such earthly wisdom is unspiritual and demonic.
Note the contrast. But the wisdom from above... Heavenly wisdom is to be pursued at all costs. Sell the house and empty the savings account to get such lofty wisdom (see Proverbs). Heavenly wisdom is characterized by purity--purity of heart, lips and life. From that purity comes peace, gentleness, reasonableness, mercy and good fruits. Heavenly wisdom is characterized as impartial and sincere.
Earthly wisdom is the opposite. It comes from a self-centered and jealous heart. Therefore it wars, is hard, unreasonable, unmerciful and produces bad fruit. It is partial and insincere. Nothing good comes from the self-centered heart.
There is coming a harvest.
Earthly wisdom produces a harvest of disorder and wickedness.
Heavenly wisdom produces a harvest of righteousness that is sown in peace by those who make peace.
Peace comes only by being reconciled to God by faith in Christ. Knowing the Prince of Peace opens the door to a lifetime of peace.
