Psalm 119:13 says, “With my lips I have declared all the judgments of your mouth.” This verse captures one fundamental reason why Christians are left on earth after they are saved. “My lips…your mouth.” What we hear from God’s “mouth” (his word/voice) is what we are to tell others. We are to speak what we know from the Lord and what we know about the Lord. The more we do his will, the more our speaking will be about him.
