Quote from A Course in Miracles Text Chapter 5 - HEALING AND WHOLENESS.

T-5.VII.1. Do you really believe you can make a voice that can drown out God's? 2 Do you really believe you can devise a thought system that can separate you from Him? 3 Do you really believe you can plan for your safety and joy better than He can? 4 You need be neither careful nor careless; you need merely cast your cares upon Him because He careth for you. 5 You are His care because He loves you. 6 His Voice reminds you always that all hope is yours because of His care. 7 You cannot choose to escape His care because that is not His Will, but you can choose to accept His care and use the infinite power of His care for all those He created by it.
