What does James 3:18 mean?

In this passage, James has been describing the difference between worldly wisdom and godly wisdom. Worldly wisdom encourages us to be selfish and greedy, and to put our own interests before the needs of others. Godly wisdom, on the other hand, leads to peace, mercy, and sincerity.

James concludes his thought from the previous verse with a beautiful word picture. Imagine fields full and ready to harvest. The crop of this field is righteousness, goodness, and everything those who belong to God would hope to see in the world.

How did it get there? The crop was planted by those who make peace. James elevates the role of peacemakers: ones committed to living peacefully in full confidence that God is providing for them. These are believers who know God is meeting every need, giving many good gifts. Such people don't feel the need to fight against others for what they need. Their peace-loving lifestyles lead to fields of righteous choices.

That's the result of living by heaven's wisdom.
