That is an insult to every person who has suffered ill health or a terminal illness. God does not "heal" every affliction. If that were true, no Christian would ever die.
This name it and claim it theology is demonic. It is witchcraft disguised as Christian Theology.
God does heal, but he heals those he chooses to heal. For instance, despite the prayers of 10,000 prayer warriors, he did not heal my daughter. He took her home. The healing she received was entirely spiritual. My only comfort is in knowing that she is with Him and that she is no longer in physical suffering.
If you really believe your "God heals everyone" theology, then you should be preaching it outside the intensive care unit of your local hospital not from the comfort of your home. You will get sick. You will die. God already knows the number of your days. You have God's promise on that one, Frank.
