The Bible does emphatically talk about law. Law is legal and systematic-a legal system in its very nature. Those who have problems with this, have difficulty with God himself. Electricity, water, air, gravity, magnetism, etc. are governed by God-given law. If this were not true, we could not survive.
Electricity always behaves in a prescribed and uniform manner.
Thank God for law. This immutable rule puts bread on the table and a roof over the head. Natural law applies to every one and is modified for no one, except in the case of first-century miracles. God is also the author of unchanging, moral law. It is wrong to murder.
