In terms of the open questions of the Old Testament and the apocalyptic promises, and the existential experience of Israel in exile and alienation, Jesus is revealed as the one who fulfills these promises. This of course can be described superficially as a proof from prophecy. But what is meant is that the person and history of Jesus have been manifested and understood as open to the future of God in a way which was characteristic of the distinctive existence of Israel among all the nations.
Moltmann, The Crucified God, Fortress 1993, p99
Election needs to be seen as a doctrine of mission, not a calculus for the arithmetic of salvation. If we are to speak of being chosen, of being among God's elect, it is to say that, like Abraham, we are chosen for the sake of God's plan that the nations of the world come to enjoy the blessing of Abraham.
