No matter how far we have come, true joy lies in acknowledging our mistakes and allowing divine love to renew us. I believe that even evil comes for a greater good, and I believe in this. Do not swear at all; not by heaven, not by earth, not by any other oath; let our 'yes' be true and our 'no' be firm. Anxiety changes nothing. We must trust in God and act wisely, without worrying unduly about the future.
