Jesus died for all people including the unbelieving Calvinists who slice and dice his holy atonement.
Jesus is the savior of the world including all people, elect and non-elect, sheep and goats, wheat and tares.
Jesus died for and saved everyone and has forgiven them of all their sins. The only reason why anyone will ever be lost is because they resist the Holy Spirit in unbelief and deliberately reject the shed blood of Christ whereby they were sanctified.
Many will end up in hell realizing they were in fact saved by the blood of Christ but they despised it and threw it away for a bowl of John Calvin's soup.
