Do you filter your water? How about your words?
Our family drinks filtered water to avoid the hordes of microscopic creatures that live in the water served by our city. We’ve found that this water tastes better, and is healthier for our bodies because it’s cleaner. The purpose of the filter is not to kill the creatures, but to capture them inside the filter and prevent us from ingesting them.
This easily applies to filtered words. The purpose in filtering your words is not to shut you up, rather to capture the offensive words inside your mouth so your spouse won’t hear them. Ephesians 4:29 says, “Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.”
Make Psalm 141:3 your prayer - Set a guard, O LORD, over my mouth; keep watch over the door of my lips! – and work with God to speak filtered words.
