'Our supreme duty is that which we owe to God, and the
next appertains to the soul. And yet these two are such loving
correlates, that though every one of the is a duty of supreme
consequence, and such as by no means we may presume to neglect or omit,
yet cannot we possibly perform any one of them without the other. So
that whosoever will serve God doth at the same time provide for his own
soul; and he that is careful for his own soul doth at the same time
serve God. So that the state of these two sovereign duties in man, is by
a certain compendious dependency and co-intention rendered very easy,
while the faithful performance of the one is a perfect consumation of
both: for by the unspeakable tenderness and mercy of God, the good we do
to our own souls is the most acceptable service and sacrifice that we
can offer unto Him.'
