The Word for today is found in Isaiah 53:5
But he was wounded for our transgressions, He was bruised for our iniquities; the chastisement for our peace was upon Him, and by his stripes we are healed.
Isaiah 53 clearly teaches that bodily healing is included in the atoning work of Christ. The Hebrew Word for “griefs” and “sorrows” (v4) specifically means physical affliction. This is verified in Matthew 8:17: This was to fulfill what was spoken through the prophet Isaiah: “He took up our infirmities and bore our diseases.
Furthermore, that the word “bore” refers to Jesus’s atoning work on the Cross is made clear by the fact that it is the same Word used to describe Christ’s bearing our sins. See, for example, 1 Peter 2:24: who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness—by whose stripes you were healed.
These texts unequivocally link our salvation and our healing to the atoning work of Calvary.
Neither is automatically appropriated however; for each provision-a soul’s eternal salvation or a person’s temporal, physical healing–must be received by faith. Christ’s work on the cross makes each possible: simple faith receives each as we choose.
Incidentally, a few contend that Isaiah’s prophecy about sickness was fulfilled completely by the one-day healings described by Matt. 8:17. A close look, however, will show that the Word “fulfill” often applies to an action that extends throughout the whole church age.
Have a blessed day, Pastor Louise.
