Lewis on his book The Problem of Pain

the only purpose of the book is to solve the intellectual problem raised by suffering; for the far higher task of teaching fortitude and patience I was never fool enough to suppose myself qualified, nor have I anything to offer my readers except my conviction that

when pain is to be borne,

• a little courage helps more than much knowledge,
• a little human sympathy more than much courage,
• and the least tincture of the love of God more than all.

(formatting mine, from the Preface of The Problem of Pain, p.xii)
