not what sin would have done to him in particular, had not Christ
the Lord, stepped in and saved, cannot know the utmost of the love
of Christ to him in particular. Sin therefore in the utmost evil
of it, cannot be known of us: so consequently the love of Christ
in the utmost goodness of it, cannot be known of us.

Besides, there are many sins committed by us, dropping from us,
and that pollute us, that we are not at all aware of; how then
should we know that love of Christ by which we are delivered from
them? Lord, "who can understand his errors?" said David (Psa
19:12). Consequently, who can understand the love that saves him
from them? moreover, he that knows the love of Christ to the full,
must also know to the full that wrath and anger of God, that like
hell itself, burneth against sinners for the sake of sin: but this
knows none. Lord, "who knoweth the power of thine anger?" said
Moses (Psa 90:11). Therefore none knows this love of Christ to
the full. The nature of sin is to get into our good, to mix itself
with our good, to lie lurking many times under the formality and
shew of good; and that so close, so cunningly, and invisibly,
that the party concerned, embraces it for virtue, and knows not
otherwise to do; and yet from this he is saved by the love of
Christ; and therefore, as was hinted but now, if a man doth not
know the nature of his wound, how should he know the nature and
excellency of the balsam that hath cured him of his wound.

2. There are the due aggravations that belong to sin, which men
are unacquainted with; it was one of the great things that the
prophets were concerned with from God towards the people, (as to
shew them their sins, so) to shew them what aggravations did belong
thereto (Jer 2, Jer 3, Eze 16).
