History is littered with examples of the power of words. Famous speeches, heartfelt letters, words of comfort , biting criticism… The results of our words can last a lifetime, for better or for worse, and don’t we know it! In the book of Proverbs we find much wise advice about how we should and shouldn’t speak in many different contexts of life. This wisdom is startlingly practical and embarrassingly convicting. Luke 6:45 states: “Out of the overflow of his heart his mouth speaks”. Ultimately what we say betrays who we really are. To be able to control our tongues requires more than will-power. It needs “heart surgery”. And only the Holy Spirit can change us in this way so that our words consistently honour God and build up others.
