Enthusiasm- en-theo-as-mos: God within us.
I love the movie, Chariots of Fire. The Christian character of Eric Liddell (sp) presented there is one of my heroes. However, I must disagree with one of the quotes as it is presented in the movie. Drawing from the verse, "The Kingdim of God is within you," Liddell goes on to say, "Where doed the power come from, to see a race through to its end? From within."
That may be true, but it is only by God working in us, and in no other way.
