amazing grace

thinking of grace today, remembering part of a sermon dr. tim keller gave not long ago (for christmas mom & dad gave me a subscription to the redeemer pres. tape ministry, which pleased me very much). he quoted a hymn i'd never heard, the lyrics of which have been running through my mind the three days since:

what though th' accuser roar
of ills that I have done
i know them well, and thousands more:
jehovah findeth none.

what i wouldn't give to not only believe that intellectually, but know it, really know it, in the marrow of my bones.
