Claiming that someone has been healed when they've actually died is one of the biggest frauds the church perpetrates on grieving family members.
Obviously, it's a comfort to tell people their loved one is now with the Lord, but don't pretend it's an honest answer to prayers for healing of a sick or wounded body.
Alongside all setting people free spiritually, from demons etc. Jesus constantly demonstrated that he healed the physical body, and when healing is talked about in scripture, it means healing the physical body.
There are other scriptures about wounded spirits, but that's a different subject.
Ultimately, nowhere do we see scripture claiming that a person is healed when he's just died. That's just a practice of con merchant Christians
You can usually tell its a lie when the body starts to stink after a day or two.
