Sounds like 'in Christ' to me...
Ephesians 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
Ephesians 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
The "us" is a reference to the group "Christian", the group "Saints", the group that is "in Christ Jesus", Eph 1:1.
The "us" is not a reference to certain individual God randomly, unconditionally chose to be in Christ.
If you agree with Stonethrower, then show us the verse that says unbelievers are saved. I can show you a verse that says unbelievers are "condemned already", Jn 3:18, so show us the verse that says unbelievers are "saved already" ie already "in Christ Jesus".
