This doctrine of dying to self is the law for every Christian, for Christ said: "If anyone wants to follow Me, let him take up his cross and deny himself." But this doctrine which seems so austere, takes on a delightful sweetness when we consider the outcome of this death - life in God in place of our life of sin and misery. This is what St. Paul meant when he wrote: "Strip off the old man and clothe yourselves anew in the image of Him who created you." This image is God Himself. Do you recall His wish which He so clearly expressed on the day of creation: "Let us make man in our image and likeness"?
