admits of degrees of knowledge: the love of Christ is knowable.
Again, that which is not possible to be known to the utmost, is
to be known, we know not how much; and therefore they that seek
to know it, should never be contented or satisfied to what degree
of the knowledge of it soever they attain; but still should be
reaching forward, because there is more to be known of it before
them. "Brethren," said Paul, "I count not myself to have apprehended,
(that is to the utmost) but this one thing I do, forgetting those
things which are behind, and reaching forth unto those things
which are before, I press towards the mark for the prize of the
high calling of God in Christ Jesus" (Phil 3:13,14). I might here
discourse of many things, since I am upon this head of reaching
after the knowledge of the love of Christ in many of the degrees
of it. But I shall content myself with few.

1. He that would know the love of Christ in several degrees of
it, must begin at his person, for in him dwells all the treasures
of wisdom and knowledge. Nay, more; In him "are hid all the
treasures of wisdom and knowledge" (Col 2:3). In him, that is, in
his person: For, for the godhead of Christ, and our nature to be
united in one person, is the highest mystery, and the first
appearance of the love of Christ by himself, to the world (1 Tim
3:16). Here I say, lie hid the treasures of wisdom, and here, to
the world, springs forth the riches of his love (John 1:14). That
the eternal word, for the salvation of sinners, should come down
from heaven and be made flesh, is an act of such condescension, a
discovery of such love, that can never to the full be found out.
Only here we may see, love in him was deep, was broad, was long,
and high: let us therefore first begin here to learn to know the
love of Christ, in the high degrees thereof.
