15 (Jesus said) Everything that the Father has is mine; that is why I said the Spirit will receive from me what is mine and will tell it to you.
16 In a little while you will see me no longer; again after a little while, you will see me.
Just as the disciples saw the Father, (through Jesus) as they walked with Jesus. (see John 14:7-9)
So we see Jesus, through the Holy Spirit as He leads and impresses our minds with truths that Jesus taught. Lifting our minds and worship to Jesus.
And yes, after a little while we will see Jesus face to face, coming in the clouds of glory, to take us to the Father's house.
Do you think Jesus in the context was referring to His second coming?
And how does that fit in with the previous statements bolded?
In the ultimate sense yes, we will literally, in person, be with God.
But in the immediate sense the Holy Spirit, having the fullness of the Godhead, brings Christ and the Father to us spiritually.
In the immediate sense both the Father and Christ are with us in the person of the Holy Spirit.
Just as the Father was with the disciples in the person of Jesus, there in the upper room.
Remember the previous verse --
Philip asks Jesus to show them the Father.
Why did Jesus answer him saying "YOU HAVE SEEN THE FATHER" "he that has seen me has seen the Father; and how say you, Show us the Father?"
Now the "oneness movement" (a Pentecostal group) claim that passage proves that God the Father and the Son are one and the same person, they say there is only one Being who changes into different phases. Father, Son, and Spirit -- are supposedly all just phases of the one being. But I believe the Godhead is three living, eternal persons, Father, Son and Holy Spirit, Who are distinct personalities, yet have a oneness we don't even begin to comprehend in which they know each others thoughts, feel each others feelings, each having all the attributes of the full Godhead within themselves, yet in perfect unity of oneness. Thus where one is present, all three are present through that one.
Example: God the Father wasn't crucified, He wasn't physically on that cross, yet, 2 Cor. 5:19 "To wit, that God was in Christ, reconciling the world unto himself." In their Oneness connection He was on the cross with Christ.
