"It is by endurance that you will secure possession of your souls (Luke 21:18). The possession of a soul means the undisturbed mastery of oneself, which is the secret of inner peace, as distinguished from a thousand agitations which make it fearful, unhappy, and disappointed. Only when a soul is possessed can anything else be enjoyed. Our Lord here meant patience in adversity, trial, and persecution. At the end of three hours on the Cross, He would so possess His soul that He would render it back to the Heavenly Father." Archbishop Fulton Sheen
