“Surely, He has borne our griefs [sicknesses] and carried our sorrows [pains]; Yet we esteemed Him stricken, smitten by God, and afflicted. 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 53:4-6). His use of our and we mean what they say.
Nowhere, does He say He picks and chooses whom to heal. These verses thoroughly detail that Jesus fully took our place or substituted Himself, taking both physical sickness and sin upon Himself. Also, note above the original Hebrew for griefs is sicknesses and sorrows is pains.”
