Make sure that what you say has intended purpose. The moment you release the words they are already in the formation to manifest in your life. Jesus did not have lot to say, His words were executed with absolute purpose. The one place He spoke a lot was in the beatitudes. We can not be ashamed of what we have to say. Let it be well thought out and approved by God.
Matthew 6:22- We must be transparent with one purpose and nothing to hide from the world that our heart be NOT divided. Anything other is evil v.23.
