natural work in restoring or healing itself.
We have been made that way.
Some sicknesses or diseases the body cannot
repair on it's own. So when we go to a doctor
for help; they can only aid in the natural work
or do a temporary fix, manage or control them.
They acknowledge that they are unable to do the
healing process, which can only come from God.
We can receive our physical salvation the same
way we received our spiritual salvation, through
faith in Jesus' work on the cross.
