Matthew 8:16-17 (NASB) When evening came, they brought to Him many who were demon-possessed; and He cast out the spirits with a word, and healed all who were ill. This was to fulfill what was spoken through Isaiah the prophet: “HE HIMSELF TOOK OUR INFIRMITIES AND CARRIED AWAY OUR DISEASES.” (ref. Isa. 53:4)
I’ve always thought of Is. 53:5 “by His stripes we are healed” as referring to our soul’s diseases. I think primarily because I’ve not seen very many physical healings. I parallel that with Psa. 103:1-3 Bless The Lord, O my soul,…who pardons all your iniquities and heals all your diseases.”
But here is a reference quoting Isaiah and saying it refers to His healing of physical illnesses and even demon possession.
My application: In prayer for physical needs, always be listening for His direction/will but don’t be shy in asking for physical healing. Temporal miracles can usher in eternal results.
(Because I do not want to pray my own ‘sympathies’, I do ask how what I’m praying might glorify God and advance His kingdom on earth as well as ‘make my joy complete’. John 16:24)
