Augustine of Hippo

Indeed, "the precepts are good," as Pelagius says, if we use them lawfully. And in virtue of our strong conviction "that the good and just God could not have prescribed impossibilities," we are admonished both what to do in easy things and what to ask for in difficult ones. Indeed, all things are easy for love, to which alone the burden of Christ is light, or which alone is itself the burden which is light.
