There should is no implication in my post about the merits of any assassinations whatsoever, but I do think that Christians today should look to Bonheoffer as one example of a man who did not sit back and hide behind the guise of, “Well, God appoints all governments so we should abide by it and not do anything.”
No. Bonheoffer did not abide by the evil government he saw and he took direct actions against it to subvert it and to destroy it. There were many Christians who fought in the Revolutionary war who did not abide by the specious doctrine that because God allows the set up of government that we should simply submit to it like sheep.
Moses was another example of a person who did not sheepishly submit to his government.
Regarding the drastic action they engaged in; they did not come to their decision easily. If I remember correctly, it was a painful struggle.
