Since Christ has suffered physically, take the same attitude that he had. (A person who has suffered physically no longer sins.)
That way you won't be guided by sinful human desires as you live the rest of your lives on earth. Instead, you will be guided by what God wants you to do.
You spent enough time in the past doing what unbelievers like to do. You were promiscuous, had sinful desires, got drunk, went to wild parties, and took part in the forbidden worship of false gods.
Unbelievers insult you now because they are surprised that you no longer join them in the same excesses of wild living.
They will give an account to the one who is ready to judge the living and the dead.
After all, the Good News was told to people like that, although they are now dead. It was told to them so that they could be judged like humans in their earthly lives and live like God in their spiritual lives.
