1 Peter 2:9-12

But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.
Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul; having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.
