Take a closer look at Isaiah 53:4-5 and meditate on the words.
"Surely (Certainly) he hath borne (suffered) our griefs (sickness), and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. 5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed." -Isaiah 53:4-5
Isaiah's prophetic words speak of how Christ's sacrifice would heal us in every area of our lives.
Jesus accomplished physical, mental, emotional and spiritual healing through the cross.
