Healing had a major place in Jesus' ministry.
Throughout His ministry He delivered all
those who were oppressed by Satan.

These deliverances included the healing of
their physical bodies.

If disease didn't come from Satan, it must
have had a place in God's plan for man.
But Matthew 8:16-17 says:
"When the even was come, they brought
unto him many that were possessed with
devils: and he cast out the spirits with his
word, and healed all that were sick:
That it might be fulfilled which was spoken
by Esaias the prophet, saying, Himself took
our infirmities, and bare our sicknesses."

And Mark 1:32-34:
"And at even, when the sun did set, they
brought unto him all that were diseased,
and them that were possessed with devils.
And all the city was gathered together at
the door.
And he healed many that were sick of
divers diseases, and cast out many devils;
and suffered not the devils to speak,
because they knew him. "
