One of the mission of Christ while on earth was healing. Isaiah the prophet saw this before time, and said
"surely he hath borne our griefs and carried our sorrows: yet we did esteem him striken, smitten of God, and afflicted. 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.
The foundation of our healing was established at the cross of Calvary, where the dying Saviour suffered for the sake of humanity. At the cross, he was wounded and bruised, and his blood gushed out as a means of that foundation which gives us full ground for our salvation, healing and other divine blessings today.
I want to tell the whole world that Satan no matter his power, cannot take away that establishment; Jesus has done it once and for all; and we have every right as a matter of fact, to receive our healing.
Matthew 4:23 And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people.
4:24 And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them.
Before His death, He has already started the ministry of healing. This healing power fully manifested after His forty days and forty night fasting. Before the fasting He has already been baptized with Holy Ghost, who strengthened Him throughout the period of the fasting
Impossible situation were broken by his healing power.
