As we grow and mature as believers, we begin to realize that we need to be careful about how we speak, even when we’re kidding around. I actually think it’s a lie of the enemy to make us think that joking is innocent. I don’t mean that all jokes are evil–of course not. But there is a line that is easily crossed when we’re joking that begins to smell of offense.
May the words of my mouth and the meditation of my heart be pleasing to you, o Lord. (Ps 19:14) May all our words be pleasing to God. When we’re angry, when we’re rushed, when we’re stressed–may we always speak what is pleasing to God.
The way to ensure that the words that come out are good is to meditate on good things. Feed your heart and mind with the life of God’s word. Let His truth fill you and your words and your thoughts become His. Fix your thoughts on what is true, and honorable, and right, and pure and lovely, and admirable.Think about things that are excellent and worthy of praise. (Phil 4:8) Take in excellence and you will give out excellence. If you start to feel guilty about what comes out of your mouth, it’s time to clean it up.
