1 Peter 1:13-16 (ESV)

¹³ Therefore, preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ. ¹⁴ As obedient children, do not be conformed to the passions of your former ignorance, ¹⁵ but as he who called you is holy, you also be holy in all your conduct, ¹⁶ since it is written, “You shall be holy, for I am holy.”
