"God never meant man to be a purely spiritual creature. That is why He uses material things like bread and wine to put the new life into us. We may think this rather crude and unspiritual. God does not: He invented eating. He likes matter. He invented it." Mere Christianity, book 2, chapter 5.
He is not a tame lion. Lion, Witch and the Wardrobe.
“Experience is a brutal teacher, but you learn. My God, do you learn.” - attributed to Lewis, possibly from the Problem of Pain.
"But how can the characters in a play guess the plot? We are not the playwright, we are not the producer, we are not even the audience. We are on the stage. To play well the scenes in which we are “on” concerns us much more than to guess about the scenes that follow it." The World's Last Night.
“To love at all is to be vulnerable. Love anything, and your heart will certainly be wrung and possibly be broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even to an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements; lock it up save in the casket or coffin of your selfishness. But in that casket - safe, dark, motionless, airless - it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. The alternative to tragedy, or at least to the risk of tragedy, is damnation. The only place outside of Heaven where you can be perfectly safe from all the dangers and perturbations of love is Hell.” - The Four Love.
"The mark of Friendship is not that help will be given when the pinch comes (of course it will) but that, having been given, it makes no difference at all."
"A young man who wishes to remain a sound Atheist cannot be too careful of his reading. There are traps everywhere -- 'Bibles laid open, millions of surprises,' as Herbert says, 'fine nets and stratagems.' God is, if I may say it, very unscrupulous."
"The term is over: the holidays have begun. The dream is ended: this is the morning."
And as He spoke, He no longer looked to them like a lion; but the things that began to happen after that were so great and beautiful that I cannot write them. And for us this is the end of all the stories, and we can most truly say that they all lived happily ever after. But for them it was only the beginning of the real story. All their life in this world and all their adventures in Narnia had only been the cover and the title page: now at least they were beginning Chapter One of the Great Story which no one on earth has read: which goes on for ever: in which every chapter is better than the one before." The Last Battle.
"Oh, Aslan!" whispered Susan...Can't we do something about the Deep Magic? "Work against the EMPEROR'S Magic?"... said Aslan with something like a frown...nobody EVER made that suggestion to Him again..."What does it mean? Is it more magic?" "It means said Aslan, that though the Witch knew the Deep Magic, there is a magic deeper still which she does not know. Her knowledge goes back only to the dawn of time. But if she could have looked further back...before Time dawned...She would have known...when a willing victim who had committed no treachery was killed in a traitors stead...Death itself would start working backward". Lion, Witch and the Wardrobe.
