There is no sanctification after death. A close look at the original Greek text overturns a cornerstone of this false gospel: Jesus did not become sin. Instead, “The one not having experienced sin took sin on our behalf in order that we might be made righteous.” The death of Christ condemned all who sin. You must become righteous and holy now, or you never will be. Would how you are living right now be acceptable in heaven? Won’t you fly to Christ, and let him make you into a new creation?
