while in the way of our duty? We have here an example worthy our
imitation. St. Paul was chiefly concerned to approve himself to God.
We should be so too--should study to acquaint ourselves with the
divine rule, and to conform to it; not disobeying God to please men.

Great care is requisite to know our duty. Enveloped in darkness, and
biassed to error, it is often difficult to find out the right way. But
we are not left without instruction. A rule is given us by which we
may "judge of ourselves, what is right." Of that role we must judge
for ourselves, and by it try ourselves. "To our own master we stand or
fall." To obtain his approbation should be our chief concern. "If God
be with us, who can be against us?"

III. Knowing ourselves fallible, it becomes us to maintain a jealousy
over ourselves, and be constantly on our guard. We should consider,
that though we do not sin wilfully, and our own hearts do not condemn
us, _yet we are not hereby justified_. We are conscious that we have
often, erred, and made wrong conclusions, when we did not design to
leave the right way. We are liable to do the same again. Our eye
should therefore be to God for direction and guidance--"That which I
know not, teach thou me; if I have done iniquity, I will do no more."

This is the more necessary, because "the light which is in us may have
become darkness." For there are those who "put darkness for light and
light for darkness." Those with whom this is the case know it not;
they flatter themselves and cry peace. "To the pure, all things are
pure; but to them that are defiled, and unbelieving, is nothing pure;
but even their mind and conscience is defiled." This often happens to
those who for a time yield to temptation and go in to the ways of sin;
they contract false principles, and judge by them, and probably
