It is patently obvious that we have gotten the atonement wrong this whole time. We keep saying things like Christ died for all but the fact is that this is completely unscriptural and dangerous. Scripture is clear about the extent of the atonement: one man.
Note that Paul explicitly points out the particularity of the atonement (Gal 2:20):
I have been crucified with Christ and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave himself for me.
