Most Christians desire to live as God intended-rich, full lives in His service. And we can. But only if we keep guard against the things in life that would drag us down.

Kurt Bruner answers by noting that these people are the ones who swim upstream-the ones who don't use circumstances or other people for living down in the dumps.
