Correction:
It changes the status of your or Christianity's assumption of the need to accept Jesus as a exclusivity to entrance into heaven.
Is no assumption:
John 14:6Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me.
John 6:28-29Then they asked him, "What must we do to do the works God requires?" Jesus answered, "The work of God is this: to believe in the one he has sent."
John 3:16For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
