"Sounds like paradise will have imperfect people... Doesn't that make it an imperfect paradise? And does anyone know what scriptures are leveraged for this second chance program?"
No it does not because being resurrected gives you the chance to become perfect in a perfect paradise. The resurrected gradually become perfect.
Also, they do not directly cite scripture for the 'second chance' teaching since they are in denial of basic Christian doctrine about the resurrection, on Judgment day, which is that of immortal souls given an immortal body and being sent to either heaven/paradise earth or to a literal hell.
