Helen Schucman,
A Course in Miracles — The Attainment of Peace
“ The body is the great seeming betrayer of faith. In it lies disillusionment and the seeds of faithlessness, but only if you ask of it what it cannot give. Can your mistake be reasonable grounds for depression and disillusionment, and for retaliative attack on what you think has failed you? Use not your error as the justification for your faithlessness. You have not sinned, but you have been mistaken in what is faithful. And the correction of your mistake will give you grounds for faith. ”
