The truth is that, just being a Christian, a believer in Jesus, will by his or her faith “confront Nero”, that is, the world. It is very Biblical because it is doing it in OBEDIENCE to God.
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.
