Healing wasn't some unusual show of His power
to convince the people of His deity, but it was
to fulfill His messiahship.
He had to heal all who came to Him for healing,
or else He would not have been true to the portrail
of Him by the Holy Spirit 700 years before.
We can't find any way to accept a Christ who does
not heal the sick. There isn't any such Christ in the
Bible.
