Darn good question.

One must not speak love out of one side of their mouth and hate out of the other. A house divided against itself cannot stand.

To love all requires you to wish ill upon none. We are all one in Creator Source; to hate any part is to hate oneself.

I once worked for a man who told me it was his Christian duty to sin as much as possible (as long as it wasn't against a member of his church...everyone else was going to be going to Hell anyway, so they didn't count) because this way when he was washed in the blood of the lamb he could claim a bigger share of redemption. It stands as the single most evil thing I have ever heard come out of someone's mouth.
