How can I reach a family member who doesn’t believe in the bible because he says that people of the old just made up religion and Jesus to control the populations. He says he is an agnostic because he believes in a god but wants proof. He says science proves dinosaurs lived millions of years ago and there are bones of people that lived about 10,000 years or longer but the Bible says that man has only been around for 6 thousand years.
The simple answer is you can’t. But the Holy Spirit can, and will provide your family member with a bonafide offer of salvation in response to your prayers. He may not accept, but he will be able to make an informed decision.
After the end times judgments there will be those who are saved and those who are not. But there will not be any agnostics and there will not be any atheists.
