Excellent response and spot on. Like the abortion debate, Liberals think giving someone the freedom to murder is good, while they acknowledge begrudgingly that the underlying the supposed "Good" is something very black and evil. The definition of moral relativism and the slippery slope of relying on Natural Law as the atheists point to.
I think you misunderstand the meaning of Natural Law; which is an 18th century term for God's laws; which are superior to any man-made codes. Some of that Law is enshrined in the Declaration of Independence: “Life, Liberty, (property) pursuit of happiness”. It was our Founders’ assumption when they framed the constitution that our people would ALWAYS conform to natural law.
Atheists eschew the concept of natural law and consider man's laws to be the ultimate standard.
Just out of curiosity, how do you know that what God says is good, or for that matter that God is good?
If you think God is good, by what standard of values are you making that judgement.
If you say God’s standard, by that method anyone or anything can claim to be good. “By my standards I am good,” says God, or anyone else.
An objective standard of good must exist before any agent can make claim to being good. Arbitrary pronouncements of good and evil are just that, arbitraty, not absolute. If your standard of good and evil are, “whatever God says is good and evil,” you do not believe in absolute values, but values based on the arbitrary whims of your God. You can have no confidence that what He says is good today, will still be good tomorrow. Since He sets the standards, He can make them anything He chooses, right?
