the alarm would be a blessing to the world.

Like the principles of spiritual religion, the principles of physical
religion are few and easy to be understood. An old medical apothegm
personifies the hygienic forces as the Doctors Air, Diet, Exercise, and
Quiet; and these four will be found, on reflection, to cover the whole
ground of what is required to preserve human health. A human being whose
lungs have always been nourished by pure air, whose stomach has been fed
only by appropriate food, whose muscles have been systematically trained
by appropriate exercises, and whose mind is kept tranquil by faith in
God and a good conscience, has _perfect physical religion_. There is a
line where physical religion must necessarily overlap spiritual religion
and rest upon it. No human being can be assured of perfect health,
through all the strain and wear and tear of such cares and such
perplexities as life brings, without the rest of _faith in God_. An
unsubmissive, unconfiding, unresigned soul will make vain the best
hygienic treatment; and, on the contrary, the most saintly religious
resolution and purpose maybe defeated and vitiated by an habitual
ignorance and disregard of the laws of the physical system.

_Perfect_ spiritual religion cannot exist without perfect physical
religion. Every flaw and defect in the bodily system is just so much
taken from the spiritual vitality: we are commanded to glorify God, not
simply in our spirits, but in our _bodies_ and spirits. The only example
of perfect manhood the world ever saw impresses us more than anything
else by an atmosphere of perfect healthiness. There is a calmness, a
steadiness, in the character of Jesus, a naturalness in his evolution of
the sublimest truths under the strain of the most absorbing and intense
excitement, that could commonly from the _one_ perfectly trained and
developed body, bearing as a pure and sacred shrine the One Perfect
Spirit. Jesus of Nazareth, journeying on foot from city to city, always
calm yet always fervent, always steady yet glowing with a white heat of
sacred enthusiasm, able to walk and teach all day and afterwards to
continue in prayer all night, with unshaken nerves, sedately patient,
serenely reticent, perfectly self-controlled, walked the earth, the only
man that perfectly glorified God in his body no less than in his spirit.
It is worthy of remark, that in choosing his disciples he chose plain
men from the laboring classes, who had
