When Did I Get in Christ Before the Foundation of the World?

The calvinist wants to camp on chose us in him. And they miss the whole idea that paul is saying, the blessing is to be holy and blameless before him at his coming. But the blessing is what that you've obtained an inheritance. Did i have the inheritance before i was born? No, i didn't even exist. I mean, i wasn't this idea of o thinking, i'm so important that i existed throughout all eternity.
