Is it at the moment of belief and justification by faith or before the foundation of the world? We are foreknown and predestined by God but are we still only placed in Christ at the very moment of belief? (belief given as a gift of course) That seems odd to me (that some parts of the body are only "added" when they believe according as they were predestined to). On the other hand, how could someone who is unrighteous be "in Christ" as "some of you" were (1 Cor 6:11)? Ephesians 1:13 does seems to suggest that we are put into Christ at the moment of belief: "In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit,"
