The Greek language, in which the New Testament was written, has two words for life. One (bios) means “mere biological existence”; the other (zoe) means “lie in all its fullness.” What we are being offered is fullness of life, which not even death itself can destroy. We are not being offered an endless extension of our biological existence, but rather a transformation of that existence.
