Do Mormons believe in modern medicine? Do they believe that God will heal them or do seek medical care?
We use doctors, medicine, and faith. We have no problems with blood transfusions, surgery, etc. We do have priesthood blessings to help the sick, as James explains (James 5: 14,15), and I’ve seen miracles occur through that power – but not always, and not according to our will.

It is my understanding that God expects us to do our best and use the resources available to us – including modern medicine – before we can expect miraculous intervention. So when people are sick, we encourage them to seek medical care, while praying for them, fasting for them, giving priesthood blessings, and generally seeking the tender mercies of the Lord to be extended toward them – but His will, not ours, be done. Among Latter-day Saints there are a number of famous doctors and surgeons, including J.
