What do such tribes reveal?...

They show the requirements of the Law (of Moses) written in their hearts, their conscience bearing witness as to what is right or wrong.

God’s eternal moral law, from which the Law of Moses was derived, never changes, whether we are speaking of the old covenant, the new covenant, or no covenant. It always has been, it is and shall continue to be, wrong and evil to bear false witness, to steal, to murder, to commit adultery.

There are instances where tribes of the earth have adopted codes contrary to these principles of right and wrong.

This is not because their hearts or consciences are different from other men, it is because demon spirits have warped their natural instincts of right and wrong.

When these spirits are cast out their natural instincts of right and wrong will be restored.
