CS Lewis on faith in the “higher sense” and “something beyond”

In Mere Christianity, after describing the first level of faith as doctrinal believing, in the next Faith chapter CS Lewis talks “about Faith in the second sense, the higher sense.” He writes that “Christians have often disputed as to whether what leads the Christian home is good actions, or Faith in Christ.” And then Lewis offers this: “A serous moral effort is the only thing that will bring you to the point where you throw up the sponge. Faith in Christ is the only thing to save you from despair at that point: and out of that Faith in Him good actions must inevitably come.” Then Lewis later concludes, “I think all Christians would agree with me if I said that though Christianity seems at first to be all about morality, all about duties and rules and guilt and virtue, yet it leads you on, out of all that, into something beyond.”
