“For out of the abundance of the heart the mouth speaks.”
— Matthew 12:34
I have heard people defend their use of God’s name as a curse by saying “I don’t mean anything by it.” And Jesus would say: that is exactly the point. The mouth speaks from what is in the heart. If the name of God flows out of you with contempt or carelessness, it reveals something about what is stored in your heart. You cannot separate the language from the life. The tongue is the overflow valve of the soul.
We live in a generation that has made vulgarity and profanity marks of sophistication. The foul-mouthed comic, the executive who curses to seem relatable, the teenager who swears to sound grown up; all of them have mistaken crudeness for authenticity. But authentic is not the same as unfiltered. A person of genuine character and genuine faith has a vocabulary that reflects what they actually believe about God, about people, and about the dignity of language itself.
I remember as a young pastor telling people: if you struggle with profanity, the answer is not more willpower. Willpower works for a while and then caves. The answer is a new heart. Jesus said “you are already clean because of the word that I have spoken to you” (John 15:3). The Word of God, taken in and meditated on, begins to change the reservoir. And when the reservoir changes, what overflows from it changes too. You cannot get clean water from a dirty well. Fill the well with clean water, with Scripture, with praise, with prayer, and what comes out of the tap will change.
Paul put it plainly in Ephesians: “Let no corrupting talk come out of your mouths, but only such as is good for building up” (Ephesians 4:29). The test for every word is not whether it is legal or socially acceptable. The test is whether it builds up or tears down. Whether it honors God or diminishes Him. Whether the people around you are stronger for having heard you speak.
What is your conversation doing to the people who hear it? Is it pointing them toward Christ? Today, let your words be a gift.
FILL YOUR HEART WITH GOD’S WORD AND LET WHAT OVERFLOWS HONOR HIS NAME.
