C. S. Lewis believes the plan of creation did indeed provide for our happiness. But something went wrong with the plan. Because must our suffering comes from other human beings. He explains: "God created things which had free will. That means creatures which can go either wrong or right. Some people think they can imagine a creature which was free but had not possibility of going wrong; I cannot. If a thing is free to be good it is also free to be bad. And free will is what has made evil possible. The more intelligent and more gifted the person God creates the greater the capacity to love and to be positive force in the universe, but also. If that person rebels, the greater capacity to cause evil, to inflict pain and to cause unhappiness. Our remote ancestors rebelled and used their free will to transgress the moral law… and to become their own masters… to invent some sort of happiness for themselves, apart from God."

Lewis asks: " why, then did God give them free will? Why in the world would God give us freedom to choose if He knew people would use that freedom to cause so much frustration in themselves and so much misery in others?" Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having." Lewis asserts that" the happiness which God designs for His higher creatures is the happiness of being freely, voluntary united to Him and to each other in an ecstasy of love and delight. And for that they must be free"
