Jesus' ministry was one of deliverance.

Not from the Romans, but from sin and
sickness.

He was to set free the spiritsand bodies
of mankind.
"The Spirit of the Lord GOD is upon me;
because the LORD hath anointed me to
preach good tidings unto the meek; he
hath sent me to bind up the broken
hearted,to proclaim liberty to the captives,
and the opening of the prison to them that
are bound; To proclaim the acceptable year
of the LORD, and the day of vengeance of
our God; to comfort all that mourn;...."
Isaiah 61:1-2

He received an anointing of the Spirit that
gave him power to perform these works.

He was not just to speak words as others
but He was to show His authority by a
ministry of power.

By binding Satan's power He would bring
deliverance.
