Be in the Resistance

I do not think any efforts of my own will can end once and for all this craving for limited liabilities, this fatal reservation. Only God can. I have good faith and hope He will. Of course, I don't mean I can therefore, as they say, "sit back." What God does for us, He does in us. The process of doing it will appear to me (and not falsely) to be the daily or hourly repeated exercises of my own will in renouncing this attitude, especially each morning, for it grows all over me like a new shell each night. Failures will be forgiven; it is acquiescence that is fatal, the permitted, regularised presence of an area in ourselves which we still claim for our own. We may never, this side of death, drive the invader out of our territory, but we must be in the Resistance, not the Vichy government. And this, so far as I can yet see, must be begun again every day. Our morning prayer should be that in the Imitation: Da hodie perfecte incipere - grant me to make an unflawed beginning today, for I have done nothing yet.
~C.S. Lewis, "A Slip of the Tongue", The Weight of Glory (1949)
