The lifting up of Christ on the Cross meant the casting down of
Satan. Satan no longer holds undisputed sway over the sons of men.
The power of darkness has been broken. Man need no longer be the
slave of sin and Satan.

d) The Question of the World's Sin is Settled:

It need no longer stand as a barrier between God and man. Strictly
speaking, it is not now so much of a _sin_ question as it is
a _Son_ question; not, What shall be done with my sin? but,
What shall I do with Jesus, which is called Christ? The sins of
the Old Testament saints, which during all the centuries had been
held, as it were, in abeyance, were put away at the Cross (Rom.
3:25, 26). Sins present and future were also dealt with at the
Cross. By the sacrifice of Himself, Christ forever put away sin
(Heb. 9:26).

e) The Claims of a Broken Law Have Been Met, and the Curse Resting
upon Man Because of a Broken Law Removed.

Col. 2:14--"Blotting out the handwriting of ordinances that was
against us, which was contrary to us, and took it out of the way,
nailing it to his cross." Thus every claim of the holy law of God,
which sinful man had violated, had been met.

Gal. 3:13--"Christ hath redeemed us from the curse of the law,
being made a curse for us: for it is written, Cursed is every one
that hangeth on a tree." (See v. 10 for the description of the
curse.) The wages of sin, and the curse of sin, is death. Christ
by His death on the Cross, paid that debt, and removed that curse.
