Matthew explains "'He Himself took our infirmities and carried away our diseases'" (Mt 8:17). He alone accomplished this at the Cross as seen that "His appearance was marred more than any man and his form more than the sons of men" (Isa 52:14). Isaiah makes it clear that "he was wounded . . . and "he was bruised" (53:5). Matthew equates it had "born our griefs" (Isa 53:4) with "took infirmities" (Mt 8:17) and had "carried our sorrows" with "bore sicknesses." This is healing language. "With his stripes we are healed" (Isa 53:5). At the same time Isaiah parallels it with Jesus being persecuted for "our transgressiions [sins] . . . and iniquities" (:5). God told Israel, "'I, the Lord, am your healer'" (Ex 15:26). He "pardons all your iniquities [and] heals all your diseases: (Ps 103:3). Peter says "He Himself bore our sins" (1Pe 2:24) and "by His wounds you were healed" (:24). Jesus spoke once when healing saying "'Your sins are forgiven you'" (Lk 5:20).
The man with leprosy cautiously implored, "'Lord, if You are willing, You can make me clean'" (Lk 5:12). Jesus then "stretched out His hand and touched him, saying, 'I am willing, be cleansed'" (:13). "Immediately the leprosy left him" (:13) Jesus told Bartimaeus, "'Go; your faith has made you well'" (Mk 10:52). The obligation was then to "'Get up, pick up your bed and go home'" (Mt 9:6). Furthermore, when Peter said to Aeneas, "'Jesus Christ heals you'" (Ac 9:34) he also directed him to "'get up and make your bed'" (:34). He had been "bedridden eight years" (:33) and maybe hardly remembered how to walk. But "immediately he got up" (:34). By faith you activate healing. Your faith is "more precious than gold" (1Pe 1:7). Do not negate the provision of the wounds of Jesus because their seriousness lays the foundation of healing for today.
