Death and life are both found in the power of your tongue. What you speak consistently over a long period of time will always come to pass. Once the words settle in your spirit and mind as a mindset, they begin to produce results for you much like a tree laden with fruits. This is why it's important for you to speak positive words based on a proven standard of verity. Choose words from the bible and make them your daily confession. If you persist on talking God's word, you'll soon start seeing little changes here and there and if you persist further, you'll see bigger changes.
