Many preachers and teachers talk as if the
healing of the body through faith was some
thing different from salvation, instead of a
part of it.

When Jesus healed the paralytic in Luke 5,
He spoke pardon to him (first things first).
"Man, thy sins are forgiven thee," then his
physical healing followed as a visible sign of
his forgiveness and evidence before all to
see that He has power to forgive sins.
