Christians: What Is the Difference?

What is the cause of natural law? To the scientist it is the order of the universe. To the faithful it is god’s design. What’s the difference other than whether god created the universe (faith) or we don’t know what created the universe (skepticism), if we all obey the natural law of reciprocity and imitation of jesus and christian charity and exhaustion of forgiveness. That’s what jefferson said, and that’s what I say and we are law givers not priests. It’s not our job to do anything other than the law that prohibits bads. That which creates goods is up to those who do not violate the law. If we obey gods law because someone in the past said we must or if we do so because the scientific evidence in all walks of life says we must, what is the difference?
