One word more: This love of our neighbour is the only door out of the dungeon of self, where we mope and mow, striking sparks, and rubbing phosphorescences out of the walls, and blowing our own breath in our own nostrils, instead of issuing to the fair sunlight of God, the sweet winds of the universe. The man thinks his consciousness is himself; whereas his life consisteth in the inbreathing of God, and the consciousness of the universe of truth. To have himself, to know himself, to enjoy himself, he calls life; whereas, if he would forget himself, tenfold would be his life in God and his neighbours. The region of man’s life is a spiritual region. God, his friends, his neighbours, his brothers all, is the wide world in which alone his spirit can find room. Himself is his dungeon. If he feels it not now, he will yet feel it one day—feel it as a living soul would feel being prisoned in a dead body, wrapped in sevenfold cerements, and buried in a stone-ribbed vault within the last ripple of the sound of the chanting people in the church above. His life is not in knowing that he lives, but in loving all forms of life. He is made for the All, for God, who is the All, is his life. And the essential joy of his life lies abroad in the liberty of the All. His delights, like those of the Ideal Wisdom, are with the sons of men. His health is in the body of which the Son of Man is the head. The whole region of life is open to him—nay, he must live in it or perish.
~George MacDonald, Unspoken Sermons
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 no 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. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having. A world of automata – of creatures that worked like machines – would hardly be worth creating. The happiness which God designs for His higher creatures is the happiness of being freely, voluntarily united to Him and to each other in an ecstasy of love and delight compared with which the most rapturous love between a man and a woman on this earth is mere milk and water. And for that they must be free.
If God thinks this state of war on the universe a price worth paying for free will – that is, for making a live world in which creatures can do real good or harm and something of real importance can happen, instead of a toy world which only moves when He pulls the strings – then we may take it is worth paying.
~CS Lewis, Mere Christianity
“That is why the real problem of the Christian life comes where people do not usually look for it. It comes the very moment you wake up each morning. All your wishes and hopes for the day rush at you like wild animals. And the first job each morning consists simply in shoving them all back; in listening to that other voice, taking that other point of view, letting that other larger, stronger, quieter life come flowing in. And so on, all day. Standing back from all your natural fussing and fretting; coming in out of the wind. We can only do it for moments at first. But from those moments the new sort of life will be spreading through our system: because now we are letting Christ work at the right part of us.”
CS Lewis, Mere Christianity
When you come to knowing God, the initiative lies on His side. If He does not show Himself, nothing you can do will enable you to find Him. And, in fact, He shows much more of Himself to some people than to others — not because He has favorites, but because it is impossible for Him to show Himself to a man whose whole mind and character are in the wrong condition. Just as sunlight, though it has no favorites, cannot be reflected in a dusty mirror as clearly as in a clean one.
You can put this another way by saying that while in other sciences the instruments you use are things external to yourself (things like microscopes and telescopes), the instrument through which you see God is your whole self. And if a man’s self is not kept clean and bright, his glimpse of God will be blurred — like the Moon seen through a dirty telescope.
–CS Lewis, Mere Christianity
