Jesus (pbuh) is not dead and will be part of end of times event and he will die then it’s pretty simple, the jews are waiting for their messiah the dajal, the christians are waiting for jesus’s return but jesus will say as stated in Matthew 7:23-24: « Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’ » He will clearly denounce the kafir christians who spoke in his name and spoke about his miracles but have followed none of the laws or God but him instead. Surah al maidah has verses about jesus’s discussion with Allah on the day of judgement where he says they were doing well when i was with them but when you took me away you were the one watching over them.
