If you keep sitting comfortably, saying that your body is healthy,
[the body’s] function will become weak and eventually you will get sick.
A healthy person is someone who runs every day even though they are tired.
It is the same with faith. If a person sits still and lives comfortably,
claiming to be fine, their constitution will ultimately become sickly.
Only when they reach their limitations later on will
they start to wriggle and move around.
