It is always God's will to heal.  Sickness is not from God to teach us.  There is not one example or teaching the New Testament that says, "Jesus sent them sickness".  He always healed, always honored faith. The key to your healing is your faith.  The woman with the issue of blood came to Jesus and Jesus said, "Your faith has made you whole".  The man lowered through the roof was healed because Jesus "Saw their faith" and honored it by raising up the man from his sickbed.  The Roman Centurion came to Jesus and said, "Just speak the word and my servant will be healed".  Jesus blessed the man with a great complement.  "Greater faith have I not seen in Israel".  Because the man understood the authority Jesus was operating under. Remember, it is God's will to give you long life and heal you.  Command sickness as a person.  It is a spirit of infirmity and command it to leave your body.  "Covid 19 go in the name of Jesus. You have no right to be in this temple of my body.  I am bought with the blood of Jesus!"  Let's walk in faith, in healing, and command sickness to leave. You have great authority in the "Name of Jesus Christ".
