Provision is made in the redemptive work of the Lord Jesus Christ for the healing of the mortal body

And when evening had come, they brought to Him many who were demon-possessed; and He cast out the spirits with a word, and healed all who were ill in order that what was spoken through Isaiah the prophet might be fulfilled, saying, HE HIMSELF TOOK OUR INFIRMITIES, AND CARRIED AWAY OUR DISEASES.

Matthew 8:16-17
