Jesus said to him, "Philip, have I been with you all this time, and yet you do not understand me? He who has seen me has seen the Father. What do you mean by saying, 'Let us see the Father'?
All has been handed over to me by my Father: and no one knows the Son except the Father — nor does anyone know the Father except the Son, and he to whom the Son chooses to reveal him.
We know that the Son of God has come, and has given us insight to know Him who is the Real God; and we are in Him who is real, even in his Son Jesus Christ. This is the real God, this is life eternal.
And who does not admit how profound is the divine truth of our religion? — it is He who was "manifest in the flesh, vindicated by the Spirit, seen by the angels, preached among the nations, believed on throughout the world, taken up to glory."
