James calls us to examine more than just what comes out of our mouths. Our words have power to build up or tear down, but they also reveal what is happening beneath the surface. The tongue becomes an indicator of the inner life, exposing the source of the wisdom, desires, and loyalties shaping us.
From our words, James moves deeper into our wisdom and our wants. Wisdom from below is marked by selfish ambition, jealousy, and disorder, while wisdom from above is pure, peaceable, gentle, merciful, and sincere. Our conflicts reveal the desires warring within us, and unchecked desires can slowly pull our allegiance away from God and toward a world organized apart from Him.
The answer is not simply better behavior, but surrender: submit to God, resist the devil, draw near to God, cleanse your hands, purify your heart, and humble yourself. Because Jesus first humbled Himself and gave Himself for us, we can surrender our words, wisdom, wants, worldliness, and will to Him.
