Depending on how you define "guns," guns were invented somewhere between AD 1000 in China and the 1860s during the American Civil War with early handguns being created in Europe in the 1500s. The Bible is silent on the issue of guns, per se, just like it does not mention computers and automobiles. Gun control is broadly considered to be the idea that a civil government can regulate how people own or use guns. The Bible may be silent on guns, but it is not silent on weapons or on government.
Some believe that guns lead to violence; others believe that guns can prevent violence. Romans 14:1–4 helps us to understand that where the Bible does not speak specifically on a subject, there is the freedom for us to choose. Therefore, gun control is not a moral or biblical issue, rather a philosophical or political issue that can and should be regularly debated, openly, honestly, and fairly. A Christian can be a proponent of gun control, believing that removing guns from the hands of people brings about peace. A Christian can be against gun control, believing that law abiding citizens are best able to protect themselves when they are armed. Whatever Christians do believe, we, as citizens, are called to submit to whatever gun ownership and use laws the government institutes. We are called to love God and love others and to pursue both peace and justice; wherever we find ourselves in the debate about gun control, we can unite on those things.
