In their book of collected essays titled ‘God and Guns: The Bible Against American Gun Culture’, C. L. Crouch and Christopher B. Hays conclude that guns are incompatible with the God of Christian Scripture. Full stop. Further, John Piper, noted Evangelical author, writes “The mindset that plans to save its life by killing is not inviting the protection of God, but the violence of man.”
I share these POV's. The single purpose of a sidearm is to inflict bodily hard on, or kill, another person.
The Second Amendment doesn’t require Christians in the US to own weapons. But Jesus does insists that we not repay evil with evil. He also tells us that 'whoever wants to save their life will lose it, but whoever loses their life for me will find it'. Go ahead and spiritualize that verse. As American Christians, it's what we do.
Don't wait for church leaders to speak with any authority on this issue. Instead, submit to the authority of Jesus, and obey his commandment that we love, not kill, our enemies.
Get rid of your guns now.
The simple things are too seldom easy.
