He has some secret source of happiness

John Angell James, "Christian Fellowship" 1822)

It is highly incumbent upon Christians, to take care against
a worldly spirit. They are in extreme peril of losing the
power of godliness from their hearts, and joining the number
of those, of whom it is said, in the expressive language of
Paul, that "they mind earthly things!"

Such earthlings look upon the possession of wealth as "the
one thing needful." Wealth is their chief object of pursuit,
the chief source of happiness. Nothing modifies or mitigates
their desire for riches. They are of the earth, earthly!

Now certainly a Christian is, or ought to be, of another spirit
than this! He should be industrious, frugal, and persevering
in his attention to the concerns of this world. But still there
should be in his mind, an ultimate and supreme regard for
the possession of everlasting life. He ought not to be slothful
in business; but then he must be fervent in spirit, serving the
Lord. He should be seen to unite the 'diligent worker' and
'sincere Christian'--and to be busy for both worlds.

The men of this world should be constrained to say of him,
"This man is as attentive to business, and as diligent in it
as we are; but we can perceive in all he does, an inflexible
regard to morality, and an invariable reference to piety. We
can discover no lack of diligence or prudence; but it is perfectly
evident, that his heart and highest hope are in heaven. He is
neither so elated in prosperity, nor so depressed in adversity,
as we are. He has some secret source of happiness, of which
we are not possessed! His eye is upon some driving force,
which we do not recognize."

What a testimony!

Who can obtain a higher one?

Who should seek less?
