The mouth of the righteous speaks wisdom,
And his tongue talks of justice. – Psalm 37:30

In Psalm 37:30, we are reminded that “the mouth of the righteous utters wisdom, and his tongue speaks justice.” This is not a description of human intellect or cleverness, but rather the natural overflow of a heart that has been saturated in the Divine. When we align our lives with God’s heart, our words cease to be weapons of ego or tools of vanity. Instead, they become a fountain of life, offering clarity in confusion and hope in despair. To speak wisdom is to reflect the light of Christ into the dark corners of our daily conversations.

True righteousness is never silent in the face of inequity. The Psalmist links wisdom directly to justice, suggesting that a godly person cannot possess one without the other. To speak justice is to advocate for the marginalized, to uphold truth when it is unpopular, and to remain consistent in our moral integrity. It requires a “tongue” that is disciplined, one that refuses to participate in gossip or deceit but instead chooses to build up and restore. Our speech carries weight; it has the power to shape the environments we inhabit. By speaking justice, we actively participate in bringing the kingdom of heaven down to earth, one word at a time.

Ultimately, the quality of our speech is a diagnostic tool for the state of our souls. We cannot consistently utter wisdom if our roots are planted in the soil of bitterness or pride. As the following verse in the Psalm notes, “the law of his God is in his heart; his steps do not slip.” The transformation of our tongue begins with the surrender of our inner life. When we hide God’s Word in our hearts, our speech becomes a natural extension of His grace. Let us, therefore, strive to be a people whose words are seasoned with salt, providing the wisdom that heals and the justice that sets the captive free.
