Just realize you are unable to address the fact that this is not glad tidings what you believe because the true gospel of salvation is delivered to everyone (unlimited atonement), and it would be a sinful thought for you tell people Jesus died only for the elect and not for everyone which not giving some people the choice.

Augustine and Calvin and Sproul (and likely Spurgeon) were unsaved. Augustine was the "father of the inquisition" and "identified Donitists as heretics...as other criminals" which verdict was death. Calvin wrote, "One should not be content with simply killing such people, but should burn them cruelly," referring to those saved out catholicism and re-baptized as believers known as Anabaptists.

Calvin believed in infant baptism. He himself can't remember when he was saved (he doesn't have to, but he never was and he doesn't have to kill those who know when they were born-again). The calvinists, lutherans and catholics all persecuted the anabaptists.

A calvinist can't deliver the gospel to the unsaved because according to them, Jesus didn't die for the non-elect. According to calvinism, if a non-elect person is told Jesus died for him, that would be a lie. A calvinist would be lying to him.
