“If any man love not the Lord Jesus Christ, let him be Anathema Maranatha.” -1st Corinthians 16:22
The word “anathema” means “cursed.” The word “Maranatha” means “the Lord is coming.” The Word of God is saying that if anyone does not want to get saved, then let him be cursed because the Lord is coming. You can try to warn people, but they ultimately must make the decision to accept or reject Christ as their own personal Saviour. If we warn people of the judgment to come and they laugh in our faces, then they are choosing to go to hell by their own freewill. They will be cursed to burn in hell if they don’t become born-again.
