1 Peter 2:24 (NASB)
and He Himself bore our sins in His body up on the cross, so that we might die to sin and live for righteousness; by His wounds you were healed.
1) He Himself refers to Jesus Christ
2) our sins refers to humanity's sin burden, thus a ransom for all.
3) bore refers to Christ carrying the burden of our sins as our sin offering, the Lamb of God.
4) in His body refers His live body being the sacrifice for humanity's sin burden.
5) we might die to sin refers to all the ones absolved of their sin burden
6) live for righteousness refers to those born anew, who are created for good works.
7) by His wounds you were healed refers to our salvation from the penalty of sin because Christ suffered and died
Since Christ laid down His life as a ransom for all, nowhere in this verse is any suggestion of limited atonement.
1 Peter 1:2 indicates Peter is addressing believers who are chosen, and existing in scattered areas.
So once again, no support for individual election before being "not a people."
