Because God Says I Am Healed, Can I Assume That I Do Not Need Medical Insurance?

No!

If you aren’t really in faith, you will not receive healing directly from God.  In that case, if you don’t have medical insurance, you will end up staying sick or maimed or even dying prematurely.  Few people reach a level of faith that would allow them to avoid all doctor or hospital visits.  If you’re one of them, that’s great.  Otherwise, you are wise to carry medical insurance.  What if some nut on the road plows into you and breaks some of your bones?   You have the right to believe for healing, of course, without a doctor, but are you really ready to do that?  (You could answer that no accident will befall you in the first place, in which case you’d better keep your faith active and drive carefully!)

Having or not having medical insurance does not determine whether you will receive divine healing – your faith does!

Jesus said that the sick need a physician (Matthew 9:12, Mark 2:17, Luke 5:31).  If you have a serious health issue, you need a doctor – either a human one (who can help you much of the time) or the Great Physician whose ability is unlimited.  If you’re not ready to receive from the Great Physician, you should go to a human one, the sooner, the better.
