Therefore to him that knoweth to do good
This may regard not only the last particular of referring all
things to the will of God, the sovereign disposer of life, and
all events, which some might have the knowledge of in theory,
though they did not practise according to it; but all the good
things the apostle had exhorted to, and the contrary to which he
had warned from, in this epistle; and suggests, that a Gnostic,
or one that knows the will of God, in the several branches of it,
revealed in his word,
and doth it not, to him it is sin:
it is a greater sin; it is an aggravated one; it is criminal in
him that is ignorant of what is good, and does that which is
evil, nor shall he escape punishment; but it is much more wicked
in a man that knows what is right and good, and ought to be done,
and does it not, but that which is evil, and his condemnation
will be greater; see ( Luke 12:47 Luke 12:48 ) . The
omission of a known duty, as well as the commission of a known
sin, is criminal.
