1 Peter 2:9-10 Part 2 of 2

But you are a chosen people, a royal priesthood, a holy nation, God's special possession, that you may declare the praises of him who called you out of darkness into his wonderful light. Once you were not a people, but now you are the people of God; once you had not received mercy, but now you have received mercy.

that you may declare the praises of him who called you out of darkness into his wonderful light 
Acts 26:17-18  " 'I will rescue you from your own people and from the Gentiles. I am sending you to them to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.' "

Once you were not a people, but now you are the people of God 
Hosea 1:9-10  Then the LORD said, "Call him Lo-Ammi (which means "not my people"), for you are not my people, and I am not your God. Yet the Israelites will be like the sand on the seashore, which cannot be measured or counted. In the place where it was said to them, 'You are not my people,' they will be called 'children of the living God.' "  
Hosea 2:23  "I will plant her for myself in the land; I will show my love to the one I called 'Not my loved one.' I will say to those called 'Not my people,'  'You are my people'; and they will say, 'You are my God.' "
Romans 9:25-26  As he says in Hosea: "I will call them 'my people' who are not my people; and I will call her 'my loved one' who is not my loved one," [Hosea 2:23] and, "In the very place where it was said to them, 'You are not my people,' there they will be called 'children of the living God.' " [Hosea 1:10]
