The apostle Paul in writing to the Ephesians said,
"Let no corrupt communication proceed out of your mouth,
but that which is good to the use of edifying,
that it may minister grace unto the hearers"
We usually read that and think, "Oh, I should only speak good words to others."
But who hears every single word you utter?
You do! You are the major hearer of everything you say.
This means that by watching what we say and making sure it is edifying, we minister grace to ourselves as well as others. So I am going to think more about the words that proceed out of my mouth plus, I'm going to think more about the words that swim around in my head.
Because I need all the grace (enabling power) I can get!
