“Whatever is in the heart overflows into speech.”
Lk 6:45 TLB
When you resort to profanity it proves the truth of God’s Word: “No man can tame the tongue. It is an unruly evil, full of deadly poison. With it we bless our God…and with it we curse men, who have been made in the similitude of God” (Jas 3:8-9 NKJV). Profane language is unbecoming to a redeemed child of God. So why do we do it? First: We lack the adequate vocabulary to express ourselves and feel we must swear in order for our words to have impact. Second: We resort to profanity to release our frustration with the situation. Either way, we’ve developed an ungodly pattern of expressing our displeasure, and we need to restrain ourselves. Jesus said: “A good person produces good deeds from a good heart. And an evil [person] produces evil deeds from his hidden wickedness. Whatever is in the heart overflows into speech.” Acknowledging that profanity resides in your heart will help you reject the idea that a curse word just “slipped” out of your mouth. The fact is it slipped out of your heart! If you’re “profanity-prone,” spend more time with God and ask Him to purify your heart and your mouth! Words are just verbal thoughts. So ask Him to help you practice mental discipline by “casting down” profane thoughts, and instead using words that bring life to your innermost being and to the lives of others (See 2Co 10:5). James writes, “Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so” (Jas 3:10 NKJV).
