How does the writer use a biblical reference to support her argument?

Well it depends on the kind of argument. But it goes the same for all kinds of arguments with a biblical basis. You can use the morals of the bible and the scripture to support your argument. For instance, when supporting the argument for Pro-life, Christians say that God made you in His eyes and that we are His children and He loves us very much. It also says that God says to not commit murder which in killing an unborn child is murder. You can take quotes directly from scripture to support this argument.
