The meaning of firstname.lastname@example.org:
Paraske: In the New Testament, the Greek paraskeuê stands for "preparation" and "preparation day" [German "Zurüstung" and "Rüsttag"] (Matthew 27:62; Mark 15:42; Luke 23:54; John 19:14,31,42) and indicates the day of preparation, the day preceding the sabbath. In all these verses, the important preparation day for the Passah is in view -
Anéstê: The Greek anístêmi means "to rise" (e.g. from the dead) or "to be raised"; of which the aorist (indicating an action occurring at a given time and only once, cp. the French passé simple) in the 3rd person is anéstê, "he is risen".
With my address email@example.com, I on purpose join my name Rüst (cf. paraskeuê, German "Rüsttag") to my aim of being ready for the second coming of Jesus, the One bodily raised from the dead* (cf. anéstê, "he is risen"), and the expectation then to be raised, as well, together with the whole Church of those belonging to him.
