Anyone who is honestly trying to be a Christian will soon find his intelligence being sharpened: one of the reasons why it needs no special education to be a Christian is that Christianity is an education itself. That is why an uneducated believer like Bunyan was able to write a book that has astonished the whole world.
C. S. LewisA man can't be taken to hell, or sent to hell: you can only get there on your own steam.
C. S. LewisThere is a difficulty about disagreeing with God. He is the source from which all your reasoning power comes: you could not be right and he wrong any more than a stream can rise higher than its own source. When you are arguing against Him you are arguing against the very power that makes you able to argue at all: it is like cutting off the branch you are sitting on.
C. S. Lewis[To have Faith in Christ] means, of course, trying to do all that He says. There would be no sense in saying you trusted a person if you would not take his advice. Thus if you have really handed yourself over to Him, it must follow that you are trying to obey Him. But trying in a new way, a less worried way. Not doing these things in order to be saved, but because He has begun to save you already. Not hoping to get to Heaven as a reward for your actions, but inevitably wanting to act in a certain way because a first faint gleam of Heaven is already inside you.
C. S. Lewis
