A natural instinct is to boil this issue down to the question, “Can I shoot my wife’s assailant?”
My answer is sevenfold.
1) This instinct is understandable. But it seems to me that the New Testament resists this kind of ethical reduction, and does not satisfy our demand for a yes or no on that question. We don’t like this kind of ambiguity, but I can’t escape it. There is, as I have tried to show, a pervasive thrust in the New Testament pushing us toward blessing and doing good to those who hate, curse, and abuse us (
Luke 6:27–28). And there is no direct dealing with the situation of using lethal force to save family and friend, except in regards to police and military. This is remarkable when you think about it, since I cannot help but think this precise situation presented itself, since we read that Saul drug men and women bound to Jerusalem (
Acts 9:1–2).
2) Our primary aim in life is to show that Christ is more precious than life. So when presented with this threat to my wife or daughter or friend, my heart should incline toward doing good in a way that would accomplish this great aim. There are hundreds of variables in every crisis that might affect how that happens.
3) Jesus died to keep that assailant from sinning against my family. That is, Jesus’s personal strategy for overcoming crimes was to overcome sinful inclinations by giving his life to pay debts and change hearts. It is no small thing that Peter based non-retaliatory suffering from unjust treatment on the atoning work of Christ as exemplary: “To this you have been called, because Christ also suffered for you, leaving you an example, so that you might follow in his steps” (
1 Peter 2:21).
4) I realize that even to call the police when threatened — which, in general, it seems right to do in view of
Romans 13:1–4 — may come from a heart that is out of step with the mind of Christ. If one’s heart is controlled mainly by fear, or anger, or revenge, that sinful disposition may be expressed by using the police as well as taking up arms yourself.
5) I live in the inner city of Minneapolis, and I would personally counsel a Christian not to have a firearm available for such circumstances.
6) I do not know what I would do before this situation presents itself with all its innumerable variations of factors. And I would be very slow to condemn a person who chose differently from me.
7) Back to the first point, it seems to me that the New Testament does not aim to make this clear for us. Its aim is a radically transformed heart that lives with its treasure in another world, longs to show Jesus to be more satisfying than life, trusts in the help of God in every situation, and desires the salvation of our enemies.
