Words of prudential wisdom from Richard Baxter:
‘In doing good prefer the souls of men before the body, ‘cæteris paribus.’ To convert a sinner from the error of his way is to save a soul from death, and to cover a multitude of sins [James v. 20],’ —And this is greater than to give a man an alms. As cruelty to souls is the most heinous cruelty, (as persecutors and soul-betraying pastors will one day know to their remediless woe,) so mercy to souls is the greatest mercy. Yet sometimes mercy to the body is in that season to be preferred (for every thing is excellent in its season). As if a man be drowning or famishing, you must not delay relief of his body, while you are preaching to him for his conversion; but first relieve him, and then you may in season afterwards instruct him. The greatest duty is not always to go first in time; sometimes some lesser work is a necessary preparatory to a greater; and sometimes a corporeal benefit may tend more to the good of souls than some spiritual work may. Therefore I say still, that prudence an an honest heart are instead of many directions: they will not only look at the immediate benefit of a work, but to its utmost tendency and remote effects.
