1 Peter 2:11 - 2:12
11 Beloved, I urge you as sojourners and exiles to abstain from fleshly lusts which wage war against the soul, 12 by keeping your conduct excellent among the Gentiles, so that in the thing which they slander you as evildoers, they may because of your good works, as they observe them, glorify God in the day of visitation.
