The cross of Calvary alone could destroy the works of the devil.

In assuming human nature that He might reach to the very depths of human
woe and misery, and lift man up, Christ has shown what estimate He
places upon the human race.  In this work everything was at stake.
Satan claimed to be the lawful owner of the fallen race; and with what
persistent efforts did he seek to overthrow Christ through his subtlety!
It was only by most desperate conflict with the powers of Satan that
Christ could accomplish his purpose of restoring the almost obliterated
image of God in man, and place his own signature upon his forehead.  It
was a desperate battle; for Satan had so long worked in league with
human intelligences as to about completely intercept every ray of light
shining from the throne of God upon the human mind.  The cross of
Calvary alone could destroy the works of the devil.  In that wondrous
sacrifice all eyes were called to "behold the Lamb of God, that taketh
away the sin of the world."  The love of Christ kindles in the heart of
all who continue to behold him.
