Quote from A Course in Miracles Text Chapter 6, Section 9 - Be Vigilant Only for God and His Kingdom.

The third step, then, is a statement of what you want to believe, and entails a willingness to relinquish everything else. The Holy Spirit will enable you to take this step, if you follow Him. Your vigilance is the sign that you want Him to guide you. Vigilance does require effort, but only until you learn that effort itself is unnecessary. You have exerted great effort to preserve what you made because it was not true. Therefore, you must now turn your effort against it. Only this can cancel out the need for effort, and call upon the being which you both have and are. This recognition is wholly without effort since it is already true and needs no protection. It is in the perfect safety of God. Therefore, inclusion is total and creation is without limit.
