is grounded.

The due regulation of the passions contributes more to health and
longevity than climate, or even the observance of any course of diet.
Our Creator has so constituted our natures, that _duty, health,
happiness_ and _longevity_ are inseparably blended in the same cup. To
suppress, and finally subdue all the passions of malice, anger, envy,
jealousy, hatred and revenge, and to exercise (till they become
familiar) all the noble passions of tenderness, compassion, love, hope
and joy, is a duty that heaven solemnly enjoins upon us, and in the
performance of which our years will be multiplied. But we must guard
not only our moral natures from the ravages of the corroding and
revengeful passions, but also our physical natures by observing the
strictest rules of temperance in _eating, drinking, cleanliness_ and
_exercise_.

The book of God commands us to "be temperate in all things." The
observance of this duty gives us a firm constitution, robust health,
and prepares us to participate in all the innocent and rational
enjoyments of life. Here we may witness the goodness of the Divine
Being in uniting our duty, happiness and interest in one; and so
firmly are they wedded together, and so absolutely does each depend
upon the other that they cannot exist alone. They are alike laid in
ruins the moment they are separated. If we trace this idea still
further, we witness the same wise arrangement, and the same
incomprehensible skill and goodness of the Author of our being in the
constitution of our mental natures. In these also he has wholly united
our duty, happiness and longevity in one. Jesus says, "Love your
enemies; bless them that curse you, do good to them that hate you, and
pray for them that despitefully use you, and persecute you, that ye
