Excellent insight. Why protest clandestine or unjust murders of a tyrant when the culture wishes to enthrone the killing of the helpless and needy? One man's murder is another man's euthanasia.
It's all just a matter of words.....perspective.
Or is it.
Is there an uncrossable line between right and wrong?
We deceive ourselves. Man continuance in "smaller" sin leads to a hardening of the heart so that he is callous towards "larger" sins. Sin no longer seems like sin. Fornication, divorce, drunkenness, etc. are all the mainstay and no one cares. So we move to greater sins like abortion, homosexuality, euthanasia.
Man always have had a history of moving that line of wrong. God has had a history of pushing it back.
