{All things have been delivered unto me of my Father}
(panta moi paredoth(8820)hupo tou patros mou). This sublime claim
is not to be whittled down or away by explanations. It is the
timeless aorist like edoth(885c) in  28:18  and "points back to a
moment in eternity, and implies the pre-existence of the Messiah"
(Plummer). The Messianic consciousness of Christ is here as clear
as a bell. It is a moment of high fellowship. Note epigin(9373)kei
twice for "fully know." Note also oul(8874)ai =wills, is willing.
The Son retains the power and the will to reveal the Father to
men.
