Let us never forget that such a truth as this cannot be learned by rote as one would learn the facts of physical science. They must be experienced before we can really know them. We must in our hearts live through Abraham’s harsh and bitter experiences if we would know the blessedness which follows them. The ancient curse will not go out painlessly; the tough old miser within us will not lie down and die obedient to our command. He must be torn out of our heart like a plant from the soil; he must be extracted in agony and blood like a tooth from the jaw. He must be expelled from our soul by violence as Christ expelled the money changers from the temple. And we shall need to steel ourselves against his piteous begging, and to recognize it as springing out of self-pity, one of the most reprehensible sins of the human heart.
