Of course, this God given right may not be based on the Bible. It could be divine revelation-God speaking to a prophet who reveals it to his/her followers. That may be the case with the NRA. By divine revelation, God may have spoken to the NRA and, in fact, given them the right to own guns. One must remember that the commandments were written in a negative tone, as in “shalt not” do such and such. So, this God given right must read, “Thou shalt not let anyone pry thy gun from thy hands.” Of course, this is open to interpretation. The problem with divine revelations is that there are too many humans in the discussion.
Law, not the Bible, backs rights. For example, Free Speech is a right backed by the constitution. The constitution backs up the right to bear arms. The constitution grants these rights, not God.
Sometimes you may hear someone say that they have a “God given right” to do whatever they want to their own bodies. Not true. There is no such right. In fact, people have limits on what they can do to their own bodies. The law does not allow suicide, taking certain drugs, extreme self-mutilation (not including piercing and tattoos), and smoking in public buildings. God does not grant rights so easily.
