Jesus took all on the cross, including our sicknesses, and He continues to save, deliver and heal us.
“When evening came, many who were demon-possessed were brought to him, and he drove out the spirits with a word and healed all the sick. This was to fulfill what was spoken through the prophet Isaiah: “He took up our infirmities and bore our diseases.” Mathew 8:16-17
Notice Jesus healed all. If you are struggling to see the manifestation of your healing, ask the Lord to show you if there are any barriers (sin, unbelief, unforgiveness, curses, occult involvement, etc). If there are barriers, they are on your side, not on God’s. Jesus removed the barrier at the cross (Jesus broke the Veil).
