The slippery slope is human, or if you will, sinful nature. It will happen, give it time. Sadly, it's a proven fact that the slope exists....witness God's people justifying something he has forbidden....in all sorts of areas...abortion is just one. When God's people, called to be holy and apart from the world, justify things such as this, we are already half way down the slope. I'm sorry, but I cannot see it any other way.
