1Peter 2:24 (NASB)
and He Himself bore our sins in His body on the cross, so that we might die to sin and live to righteousness; for by His wounds
you were healed.
1) Christ died for all humankind, providing a ransom for all.
2) Only those God transfers into Christ are saved by His sacrifice. Those never transferred into Christ were never saved.
3) Thus the "you" refers only to those placed in Christ.
Here again is the actual gospel:
God loved humankind in this way, He gave His one of a kind Son so that everyone believing into Him shall not perish, but have eternal life.
Thus
Christ's death did not save everyone, but did provide the means of salvation to everyone believing into Him.
To believe into Him means the person's faith was credited as righteousness by God and
therefore God put them into Christ.
Everyone God puts into Him shall not perish, but have eternal life.
The Gospel of Christ.
