A considerable weight is given in Christian doctrine and tradition,
to the concept of a God who intervenes in human affairs to heal the sick.
A more considered approach must realise that this is unrealistic.
Where healing does occur it derives from mental assent
to the charisma of the healer; to faith in his power,
or from a belief in literal biblical inerrancy
or the common view that there is a link
between sickness and sin.
