1 Peter 2:9-10 YLT

9 and ye [are] a choice race, a royal priesthood, a holy nation, a people acquired, that the excellences ye may shew forth of Him who out of darkness did call you to His wondrous light;
10 who [were] once not a people, and [are] now the people of God; who had not found kindness, and now have found kindness.
