[Protagoras]

Quoting scripture to the purposely Godless is pointless.

It won't keep them from quoting it to you however. And interpreting it.

[Raycpa]

It was mostly for you.

The relativist argument that without revelation, the law is unknowable is something I once accepted as logical until I understood it isn't biblical. If something is true, it can be discovered with other methods.

I believe the concept that non Christians cannot know law is unbiblical. Apparently it is in their hearts too. They have the knowledge and conscience to know that they fall short of the law.

By understanding the law exists and that they fall short of it, they end up guilty and in need of a savior.
