C.S. Lewis

I came across an interesting quote from C.S. Lewis. This quote comes from his last sermon, titled "A Slip of the Tongue." Lewis says: "Our temptation is to look eagerly for the minimum that will be accepted. We are in fact very like honest but reluctant taxpayers. We approve of an income tax in principle. We make our returns truthfully. But we dread a rise in the tax. We are very careful to pay no more than is necessary. And we hope - we very ardently hope - that after we have paid it there will still be enough left to live on."
Later Lewis adds these words: "It is not so much of our time and so much of our attention that God demands; it is not even all our time and all our attention; it is ourselves. For each of us the Baptist's (John the Baptist) words are true: 'He must increase and I must decrease.' He will be infinitely merciful to our repeated failure; I know of no promise that He will accept a deliberate compromise. For He has, in the last resort, nothing to give us but Himself; and He can give that only insofar as our self-affirming will retires and makes room for Him in our souls. Let us make up our minds to it; there will be nothing "of our own" left over to live on, no "ordinary life."... He claims all, because He is love and must bless. He cannot bless us unless He has us. When we try to keep within us an area that is our own, we try to keep an area of death. Therefore, in love, He claims all. There's no bargaining with Him."
