Believe on the Lord and you will be Saved

Dear Savvy, my father is almost 90- years old and recently had a minor stroke. I fear he will not live too much longer. He never truly accepted Jesus as his Savior. My family does not go to church and they do not know the Bible. I want someone to talk to him about Jesus so he can accept Jesus as his Savior. My family says he is too stubborn and will never change. They don't seem to care if he goes to heaven. In fact, they believe if you are just a good person that you will go to heaven.
