Answer: Read carefully what Paul says in Romans 2:14-15 : Indeed , when Gentiles , who do not have the law , do by nature things required by the law , they are a law for themselves , even though they do not have the law , since they show that the requirements of the law are written on their hearts , their consciences also bearing witness , and their thoughts now accusing , now even defending them .
