The perfect tense-form verb ἀναβέβηκεν in John 3.13 is usually interpreted in light of traditional verb theory, as a ‘past action with present results’. This interpretation introduces an apparent problematic chronology in that the Son of Man ascends before descending; however, recent developments in Greek grammar, particularly verbal aspect theory, provide a viable solution to this grammatical ‘problem’ and indicate that the Son of Man's descent precedes his ascent.
