When religionistas gets on about "You can't have morality without God", here's the perfect response, right out of their own book, courtesy of
Paul's letter to the Romans (New Living Translation)
Even Gentiles, who do not have God’s written law, show that they know his law when they instinctively obey it, even without having heard it. 15They demonstrate that God’s law is written in their hearts, for their own conscience and thoughts either accuse them or tell them they are doing right. (Romans 2:14-15)
So there you go. God's "Law" is nothing more than what people do anyway, when they don't even know his old law exists. All the Bible has is shit we already know, so there's no point in even having it, and it's not heathen old me saying it, that's directly from the founder of the church.
So bookmark this passage and next time some Jesus Junkie starts with this tired old argument you can shoot him down with a quote from his own Founding Father. ROFL!
