Proverbs 19:21

Death and life are in the power of the tongue, and those who love it and indulge it will eat its fruit and bear the consequences of their words. 

Life comes from the word of God! A faith life is built up on believing and speaking the word. A life that chooses and uses the word every day creates a faith foundation. The more we practice our faith, the stronger the power of that faith against our circumstances. We cannot be passive in our faith but active doers of the word.
