Rather, he's contrasting our ability to relate to others. The ability to forgive, submit to, and keep peace with another is a sign that godly wisdom is present in your life. An inability to do so, combined with fighting, argumentation, and gossip is a sign that you operate through earthly wisdom--a wisdom that looks out for yourself instead of others.
James teaches us (3:13-4:3) that godly wisdom is based on action that recognizes God's concern for others and is rooted in dependency on God. He also teaches us (1:5) that if we don't have this wisdom but we desire it, all we need to do is ask God, and God, who is not looking to show partiality or judge, will give his wisdom freely to those who ask.
What would be different in your life, family relationships, work relationships, or friendships if you treated those people with godly wisdom?
