Suffering and sin. (John 9 )

 In John 9 we read how our Saviour and His disciples came upon a man blind from birth,and his disciples asked the Lord,'Who sinned,this man or his parent,that he was born blind' and the Lord replied ,'neither this man or his parents',There was a reason the disciples asked that question, here was a man blind from birth,it appears some Jewish theologians  had a stange notion of prenatal sin,in other words he sinned in the womb.so Jesus cut across that thought.What about his parents ? Jesus cut across that thought also.It is interesting that Hindu and Buddhist religions believe in moralistic cause and effect,that an individual is personally culpable for their current station in life,whether incurred in this life or one previous.I heard a young who had cancer being told that the reason he has cancer, was because he had sin in his life.I know that sin can cause us suffering because it has conquences.But this does mean in anyway that we have sinned,it does not mean that because one is born in poverty,dire circumstances disabilities etc,that it is beause we have sinned.,not so.But as regards sin we all sin everyone of us, yes that blind man was a sinner nothing to do with his blindness,Jesus did heal him of his blindness ,and even greater news,as a sinner he trusted Jesus as his Saviour,why don't you do that .
