Words. Empowered Spirit filled words are the key to life. They bring health to the whole body not just because you read them or you heard someone preach about them, but because you meditate on them and chew them like food. They get down in your spiritual belly (Faith doesn't work in the head, only the heart) and then it causes you to act on what you now believe. The results must be seen.
Thank you, Lord God, for the power, love, and grace that is expressed through your word. I esteem value to your word and, in the name of Yah-shua (Jesus), I receive their truths by faith to work in me now that I may be, have, and do abundantly in accordance to the good pleasure of Your will and to the building of Your Kingdom.
