John 16:28

I came out from the Father (exhlqon ek tou patro). Definite act (aorist), the Incarnation, with repetition of ek (out of), while in verse 27 we have para tou patro exhlqon) with no practical distinction between ek and para in resultant idea. Am come (elhluqa). Perfect active indicative of ercomai, as in 18:37 . The Incarnation is now a permanent fact, once only a blessed hope ( 11:27 ). His leaving the world and going to the Father does not set aside the fact of the Incarnation. Both apihmi (I leave) and poreuomai (I go) are futuristic present indicatives.
