Note 2 at Mt 8:17: The fact that this verse substitutes "infirmities" and "sicknesses" for the words "sorrows" and "griefs" in Isa 53:4 makes it clear that when Isaiah said "with his stripes we are healed" (Isa 53:5), he was speaking of the physical healing of our bodies. Jesus provided for physical healing as well as forgiveness of sins. The very word "save" (Greek - "SOZO") is translated "made whole" in reference to physical healing in Mt 9:22, Mr 5:34, and Lu 8:48. Jas 5:15 says the prayer of faith shall save (Greek - "SOZO") the sick. Many scriptures mention the healing of our bodies in conjunction with the forgiveness of our sins (Ps 103:3, Isa 53:4-6, and 1Pe 2:24). Healing is a part of our salvation, just as much as the forgiveness of our sins.
