liberty and servitude:--

A Christian man is the most free lord of all, and subject to none; a
Christian man is the most dutiful servant of all, and subject to every
one.

Although these statements appear contradictory, yet, when they are found
to agree together, they will make excellently for my purpose. They are
both the statements of Paul himself, who says, "Though I be free from
all men, yet have I made myself servant unto all" (1 Cor. ix. 19), and
"Owe no man anything, but to love one another" (Rom. xiii. 8). Now love
is by its own nature dutiful and obedient to the beloved object. Thus
even Christ, though Lord of all things, was yet made of a woman; made
under the law; at once free and a servant; at once in the form of God
and in the form of a servant.

Let us examine the subject on a deeper and less simple principle. Man is
composed of a twofold nature, a spiritual and a bodily. As regards the
spiritual nature, which they name the soul, he is called the spiritual,
inward, new man; as regards the bodily nature, which they name the
flesh, he is called the fleshly, outward, old man. The Apostle speaks of
this: "Though our outward man perish, yet the inward man is renewed day
by day" (2 Cor. iv. 16). The result of this diversity is that in the
Scriptures opposing statements are made concerning the same man,
the fact being that in the same man these two men are opposed to one
another; the flesh lusting against the spirit, and the spirit against
the flesh (Gal. v. 17).

We first approach the subject of the inward man, that we may see by what
means a man becomes justified, free, and a true Christian; that is, a
