Understanding election and Peter’s audience for the letter of 1 Peter.
“The verbal adjective ‘elect’ is passive, marking the readers as the objects of the electing action of God, who is the unnamed agent. They were chosen by God to be His own in order that they might be partakers of the heavenly inheritance being reserved for them (1:4). United by faith with Christ, the ‘corner stone, elect, precious’ (2:6, ASV), they constituted ‘an elect race’ (2:9). As God’s elect people, they formed a group separate and distinct form the world and subject to its hatred and persecution. In themselves they were just ordinary people, not superior to their unsaved neighbors; but the initiative of God made them what they are.”
