It is true that the Bible is written about 3500 to 2000 years ago by about 40 authors inspired by God.
Pharaoh was god 3500 yrs ago. Moses lived in his home, per bible/torah.
And these are in essence a rollout of new information with each book.
Evidence of an evolution (the process here in nature by man)
Many Christians make the mistake of not taking that into account when studying scripture and determining doctrine.
Yes, many make the same mistake (s)..... even in the current generations.
And yes the NT is distinct from the OT. The OT was the law and the promise of the sacrifice of Christ on the cross for the payment of the sins of all.
No sacrifice takes away or undoes sins. Keeping the the rules of personal responsibility is good no matter what time period. Try it!
The NT is the record of that, the early history of the church and the doctrine of the church.
reminds me of a true set of words: "Many Christians make the mistake of not taking that into account when studying scripture and determining doctrine."
John the Baptist said this which shows the NT (grace) replaces the OT (law).
The laws are still solid: ""18 “Why do you call me good?” Jesus answered. “No one is good—except God alone. 19 You know the commandments: ‘You shall not murder, you shall not commit adultery, you shall not steal, you shall not give false testimony, you shall not defraud, honor your father and mother.’
For the law was given by Moses, but grace and truth came by Jesus Christ. - John 1:17
Jesus was graceful............. He knew, that HE was not the importance but that each should keep the rules. See above.
