Luke 6:45 says, "The good man brings good things out of the good stored up in his heart, and the evil man brings evil things out of the evil stored up in his heart. For out of the overflow of his heart his mouth speaks.” Where do things that are stored in our hearts come from? They come from WORDS! Words that originate from God or words that originate from the enemy. As these words are stored in our heart, there will come a time when they will come out of our mouths...that is when we have the power to create worlds & to bless or curse. James 3:2 says, "For we all stumble in many things. If anyone does not stumble in word, he is a perfect man, able also to bridle the whole body…” So the key to holiness is taming our tongues.
