Everything is spiritual

C.S. Lewis on why it's not feasible or wise "to become exclusively and explicitly religious":

Before I become a Christian I do not think I fully realized that one's life, after conversion, would inevitably consist in doing most of the same things one had been doing before, one hopes in a new spirit, but still the same things...Conversion [does not] obliterate our human life...

All our merely natural activities will be accepted, if they are offered to God, even the humblest, and all of them, even the noblest, will be sinful if they are not. Christianity does not simply replace our natural life and substitute a new one; it is rather a new organization which exploits, to its own supernatural ends, these natural materials. (The Weight of Glory)

Edward Curtis and John Brugaletta comment, "Becoming a believer then does not wall off the secular from the sacred; it does however require that all worldly activities be performed with God in mind and then offered up to God - done for His glory." (Discovering the Way of Wisdom)
