And in return for what do they receive such things? For the covering of a roof, for a garment, for bread, for cold water, for visiting, for going into the prison. For indeed in every case it is for what is needed; and sometimes not even for that. For surely, as I have said, the sick and he that is in bonds seeks not for this only, but the one to be loosed, the other to be delivered from his infirmity. But He, being gracious, requires only what is within our power, or rather even less than what is within our power, leaving to us to exert our generosity in doing more.
