HarleyD God doesn’t use sickness to teach you something. God said He wants you healthy 3John 2. God is a healer.
That is not what God told the apostle Paul, Marian, or Job. Paul prayed three times but was never cured from his affliction. Marian was turn to a leper for a week after criticizing Moses. Moses pleaded with God but God wanted her to understand the gravity of her rebellion before healing her. She sat outside the camp for one week as a leper. Job was afflicted with sores and boils along with a number of other problems so that he may better understand God’s sovereign control over our lives.
There are many more examples throughout scriptures. 3 John 2 is nothing more than a salutation like saying, “Hope everything is well.”
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.
