How is it obedience to God to confront Nero? Jesus told us to "Resist not evil". In the Lord's Prayer, He has us asking to not be led into temptation, but to be delivered from evil. He never tells us to confront Nero/Satan - He infers that our job is to resist the temptations of evil that we not aid and abet it. God can/will/has defeat/defeat/defeated Evil and only He can do so - all we can do is gnash our teeth, tear our clothes, and pour ashes on our heads while becoming diverted from the only thing we can do - carry the Word and do our best to not be sucked into the evil that abounds.
I need to disagree with you on this.
Plus take a look at a few posts, one of which I had posted, there are those in the Bible that did confront, they did it for love and obedience to God.
Doing so is simply saying NO to Nero/Satan, YES to God/Jesus. This is not to mean get violent, just standing up to Godly principles.
