e members of Christ." The body "is for the Lord, and
the Lord for the body." "Your body is the temple of the Holy Ghost,
which is in you, which ye have of God." "If any man defile the temple
of God, him will God destroy." Yield "your members as instruments of
righteousness unto God." Sin is not to "reign in your mortal body."
"Glorify God in your body." We are to "present our bodies a living
sacrifice, holy, acceptable unto God, which is our reasonable service."
(_d_) The body is a part of that humanity which Christ by His
_incarnation_ took, redeemed, sanctified and glorified. (_e_) Our
Lord's miracles were nearly all performed on the human body, for its
relief, cure, and restoration to life.

IV. To a certain extent our health is in our own hands.--Not
altogether, for some are constitutionally defective, and subject to
infirmities with which they are born, and which they have perhaps
inherited. But a vast amount of disease is preventable, and comes from
causes over which we have direct control. "It is reckoned that a
hundred thousand persons die annually in England of preventable
diseases"--from disobedience to the laws of health, which are God's
laws, and the transgression of which, wilfully, is sin. Beyond all
doubt a vast amount of sickness comes from bad living, from
intemperance in eating and drinking, from breathing bad air, from
inhabiting ill-constructed houses. It is possible to live in
accordance with the laws of health so that life may be comparatively
free from disease and from pain. If Providence denies health, the want
of it must be patiently endured. If we have inherited weakness, we
must make the most of the strength we have. But if we lack health
through our own fault we are guilty of shameful sin.

To discuss fully the subject and laws of health would require a whole
treatise, and would be beyond the scope of this text-book. There are,
however, some outstanding conditions for the preservation of health
which are plain to everyone, and which may be summed up in the three
words Temperance, Exercise, and Rest. These have been well termed the
three great physicians, whose prescriptions are painless and cost
nothing.

1. _Temperance_.--Man needs a certain amount of food to sustain him,
but if that amount be increased beyond the proper quantity it is
dangerous to health. It overtasks the power of digestion and is
injurious. We need therefore to be constantly on our guard as to what
