How important it is to know, that what you speak is the direction your life will go. Starting from the Old Testament and going on to the New, we find this LAW to be accurate and true. In the beginning God created the heavens and the earth by what he spoke. Look how many times it was repeated, “and God said.” Words are what make you like God, only you are a free will agent, and have the ability to speak however you please. If you begin to speak inline with the word of God, you will farewell in this life, and the next.
Matthew 10:32-33 King James Version (KJV)
32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.
33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
