The Christian man in his present state is like a bird in a cage:

His body imprisons his soul.

His spirit, it is true, ranges heaven and earth, and laughs at the limits of matter, space, and time;

but for all of that laughter, the flesh is a poor scabbard unworthy of the glittering soul, a mean cottage unfit for a princely spirit;

this body is a cog, a burden, a fetter.

-Charles H. Spurgeon
