Prologue to the Rule (paragraph 6)

For that very reason also, so that we may mend our evil ways, the days of our mortal lives are allowed us as a sort of truce for improvement.

(From para. 6 of the Prologue to Saint Benedict's Rule, trans. by Patrick Barry OSB, 1997.)

I'm not sure, but I think the word truce is related to the word trust, or the word truth.  God offers me the truce of my entire life, because God absolutely trusts me to find him, in Spirit and in truth.
