Here we have, 1. The ill consequences of betraying a trust. A wicked
messenger, who, being sent to negotiate any business, is false to him
that employed him, divulges his counsels, and so defeats his designs,
cannot expect to prosper, but will certainly fall into some mischief or
other, will be discovered and punished, since nothing is more hateful
to God and man than the treachery of those that have a confidence
reposed in them. 2. The happy effects of fidelity: An ambassador who
faithfully discharges his trust, and serves the interests of those who
employ him, is health; he is health to those by whom and for whom he is
employed, heals differences that are between them, and preserves a good
understanding; he is health to himself, for he secures his own
interest. This is applicable to ministers, Christ's messengers and
ambassadors; those that are wicked and false to Christ and the souls of
men do mischief and fall into mischief, but those that are faithful
will find sound words to be healing words to others and themselves.
