"For I think that God hath set forth us the apostles last, as it were appointed to death: **for we are made a spectacle unto the world, and to angels, and to men**."
Paul the Apostle, 1 Corinthians 4:9

So

Yes or no?

Yes we do have the duty, however we cannot do it in fully in our sinful state. We must let God's Son do it for us.

Which means what

By letting Christ's divine character manifest in your actions, speech, personality, etc. you will reflect the character of God -- who has never sinned.

Which means what

I'm not sure what you're asking.

I'm asking you what that means practically

I get that it's a conveniently flattering position to hold rhetorically

If you're not Christian, it seems like rhetoric. But if you do believe in the Gospel, you understand Jesus was the Passover Lamb for the Jew and Gentile. Meaning, by believing in the merits of a crucified and risen savior, you can overcome sin through Christ. Not your own works.

Yeah well again that's convenient rhetoric

Because that doesn't actually tell me anything

Relevant to the question

"Christians" are those who follow Christ -- the anointed one. Practically, your life should resemble the life of the Son of God.

What
Does
That
Entail

Cause I could give you an extremely clear answer

You don't seem capable of that

Living in accordance with the Ten Commandments.

Ok good.

I apologize if I'm not being clear. I assumed you knew the character of Christ already. And how he never sinned, and fulfilled the law.

If you don't know these things, then yes what I said earlier may have seemed like rhetoric. It's not.

I do know these things

This is how people who don't have answers speak - sanctimoniously

If there is a moral law which we know and man has no right to error then why would we enthrone as good, right and desirable policies which oppose that moral law?

Jesus kept the ten commandments. Those who follow Christ do as well.

"Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus."
Revelation 14:12

For the same reason God didn't smite Satan.

He rebuked Satan

he was cast from heaven
removed from the life of grace

He will smite Satan, but only after he has fulfilled his purpose: Exposing evil to the angels who never knew sin.

he was clearly punished

we know from sacred scripture that at the final judgement Satan will be punished and those who reject God will also be punished

See what I said above

And so justice is clearly a virtue

I agree

So why should we not follow that virtue

Because you can say that God allows evil to persist for his own providential ends (which I agree) but he also clearly desires the salvation of man and Christ warns those who would corrupt the faith of others

And he does that through his servants, who observe the sixth commandment.

What the government does should be based on the well being of the state. Letting crimes go unpunished is detrimental to the state. That is separate from what individual Christians should do.

How can what is good for individuals be bad for the State
