"Christians should ultimately do everything that we do with excellence. There's a story about repairs in the Sistine Chapel ... when some repair work was being done the craftsmen saw that the work on the other side of the plaster, the part not visible to the human eye was done with the same kind of craftsmanship that was done on what was visible and observable. And the explanation for that is that the work that Christians do is not just for human consumption, but it is also for the eyes of God."
