Peter says the Christians suffering at the hands of sinners is due to the Christian’s lack of participation in sinful activities. If you suffer because you did something wrong, there is no honor in that. If you suffer for doing the right things, that’s an honor.
There can be a fine line between suffering for the right or wrong reason sometimes. Suffering because you refused to do something wrong is honorable. Suffering because you are disrespectful of those who do wrong things isn’t.
