"Be not grieved if thou performest it thyself alone. Let God be all-sufficient for thee."

"Be not grieved if thou performest it thyself alone. Let God be all-sufficient for thee. Commune intimately with His Spirit, and be thou of the thankful. Proclaim the Cause of thy Lord unto all who are in the heavens and on the earth. Should any man respond to thy call, lay bare before him the pearls of the wisdom of the Lord, thy God, which His Spirit hath sent down unto thee, and be thou of them that truly believe. And should anyone reject thine offer, turn thou away from him, and put thy trust and confidence in the Lord, thy God, the Lord of all worlds."
