As an “old believer” you will have a final opportunity to accept the truth you currently reject. The bad news is that those seven years are going to be quite painful for you. See you on the other side.
This is what chr*stianity (at least American Fundamentalist Protestantism) believes. I understand that. Please just understand that from my point of view it is good chr*stians who will convert (not to Judaism, but to Noachism).
And I'm not Jewish. I'm a Noachide.
