In other words, The­ol­ogy is prac­ti­cal: espe­cially now. In the old days, when there was less edu­ca­tion and dis­cus­sion, per­haps it was pos­si­ble to get on with a very few sim­ple ideas about God. But it is not so now. Every­one reads, every­one hears things dis­cussed. Con­se­quently, if you do not lis­ten to The­ol­ogy, that will not mean that you have no ideas about God. It will mean that you have a lot of wrong ones — bad, mud­dled, out-of-date ideas. For a great many of the ideas about God which are trot­ted out as novel­ties to-day are simply the ones which real The­olo­gians tried cen­turies ago and rejected.

The spirit of Christ is the spirit of missions. The nearer we get to Him, the more intensely missionary we become.

The perfect church service would be one we were almost unaware of. Our attention would have been on God.

His Omnipotence means power to do all that is intrinsically possible, not to do the intrinsically impossible. You may attribute miracles to Him, but not nonsense. This is no limit to His power. If you choose to say, ‘God can give a creature free will and at the same time withhold free will from it,’ you have not succeeded in saying anything about God: meaningless combinations of words do not suddenly acquire meaning simply because we prefix to them the two other words, 'God can.' It remains true that all things are possible with God: the intrinsic impossibilities are not things but nonentities. It is no more possible for God than for the weakest of His creatures to carry out both of two mutually exclusive alternatives; not because His power meets an obstacle, but because nonsense remains nonsense even when we talk it about God.

In the same way a Christian is not a man who never goes wrong, but a man is enabled to repent and pick himself up and begin over again after each stumble--because the Christ-life is inside him, repairing him all the time, enabling him to repeat (in some degree) the kind of voluntary death which Christ Himself carried out." - Mere Christianity

In God you come up against something which is in every respect immeasurably superior to yourself. Unless you know God as that-and, therefore, know yourself as nothing in comparison-you do not know God at all.
