People keep harping on about the Jews being God's chosen people as if that's the only truth in scripture... Peter says otherwise:
1 Pet. 2:4-10 (ESV)
4 As you come to him, a living stone rejected by men but in the sight of God chosen and precious, 5 you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. 6 For it stands in Scripture:
“Behold, I am laying in Zion a stone,
a cornerstone chosen and precious,
and whoever believes in him will not be put to shame.”
7 So the honor is for you who believe, but for those who do not believe,
“The stone that the builders rejected
has become the cornerstone,”
8 and
“A stone of stumbling,
and a rock of offense.”
They stumble because they disobey the word, as they were destined to do.
9 But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. 10 Once you were not a people, but now you are God's people; once you had not received mercy, but now you have received mercy.
The Church is now God's chosen people; Holy and precious, a holy nation, His own possession.
