The love of a father to a son is what is been displayed here, the bond the father has for the son is what is keeping the boy still alive. from the article the father has refused for the life support machine to be removed, signalling that he believes by divine intervention, his son will resuscitated back to life. Medically I don't how possible it is for a brain that has remained in coma for over a decade to be well functional if he wakes up again.
