We have to learn that we are not agents to act for the Lord so much as instruments by which He acts—pipes through which He waters. We must learn our nothingness in order that we may be simple, in no way occupied with ourselves, whether in success or failure. Our work is to deliver our message, and we are rewarded for doing our work—the success is not ours to control. When we learn our nothingness, that we are only the instruments which He takes up as and when He pleases, and for what He pleases, we shall be content to work on simply.
