I abhor your theology, which denies the efficacy of Christ’s atoning death.
I fear for your eternal soul.
Au contraire, I think Christ's atoning death is wonderfully efficacious.
But if you think your salvation depends on deceiving God the Father by putting you under some sort of "cloak" and smuggling you into heaven with your sins concealed but still intact, not even Christ's atoning death will suffice for that.
Because, you know, neither Jesus nor his righteousness can lie, nor can it cover a lie, nor can it perpetrate a lie.
Jesus identified for us in the Gospels the "father of lies". Who did he say was the father of lies?
