As you can see, metaphysical questions become practical very quickly. The essential question John brings out is this: What is the non-biblical basis for a universal, transcendent law? If you deny biblical authority, then you deny divine law, which is transcendent and universal (cf. Romans 2:15, God wrote His law on the heart of every individual). So, here are a few questions for the comment thread:
First, how do naturalists/evolutionists explain the existence of a universal law, a standard that applies to everyone?
Second, if they deny a universal standard, how do naturalists/evolutionists hold anyone accountable for their actions? That is, what allows them to condemn the actions of Marquis de Sade, Hitler, or Ted Bundy?
Third, how do naturalists/evolutionists betray their reliance on God’s law, written in their hearts?
