The Source of All Help

C.S. Lewis 

You may say 'I've never had the sense of being helped by an invisible Christ, but I often have been helped by other human beings'. This is rather like the woman in the first war who said that if there were a bread shortage it would not bother her house because they always ate toast. If there is no bread there will be no toast. If there were no help from Christ, there would be no help from other human beings. He works on us in all sorts of ways: not only through what we think of as our 'religious life'. He works through nature, through our own bodies, through books, sometimes through experiences which seem (at the time) anti- Christian. 

When our young man who has been going to church in a routine way honestly realizes that he does not believe in Christianity and stops going—provided he does it for honesty's sake and not just to annoy his parents—the spirit of Christ is probably nearer to him than it ever was before. But above all, Christ works on us through each other.
