God not only cares about what we talk about, but also how and why we say it. He desires that our speech be marked by grace—gracious, kind, encouraging, and uplifting—and not the world’s patterns. Drawing from Ephesians 4:29 and Colossians 4:3-6, this study reveals that our speech should also share the “mystery of Christ” and edify others. Ultimately, when our voices flow from hearts filled with God’s grace, they become powerful testimonies that lift up the Lord and draw others to salvation.
