"If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?"
There is simply too much hate in the world today, particularly in certain parts of the world, among certain groups of people who hold certain extreme religious beliefs. If what they do is in the name of God, then killing their brothers disproves their real motives and gives the lie to their religious convictions (if they really hold any in the first place, i.e.).
Today, it is risky to venture out of your own homes, even into your own back yard. You may be shopping happily, as the people in India's New Delhi, not doubt, were to celebrate their Deepavali. But in the blink of a eye, children have become orphans, families have lost a precious son or daughter, plans are wrecked and the joyous occasion has turned into a nightmare that will likely come back to haunt victims' relatives for years to come.
There is no salvation in hatred and selfishness, only eternal perdition. How ironic that those who long for and are promised heaven have prematurely entered hell.
