If there is a God, why do children suffer ? Millions of children in the world are malnourished, hungry, shivering in the cold, without proper clothes, with diseases caused by poverty, illiterate,and homeless. If there is a God, who is all powerful, why does he not give these children food, clothes, medicine, good education and shelter ?
And don't tell me that it is because in their previous births these children did bad deeds. Because then for proving one thing viz. the existence of God, you are presupposing two other things (1) the existence of soul, and (2) its transmigration.
