Here is Arthur McGill on what he calls the ‘ec-static’ identity of Jesus. You’ll note something like eternal generation standing in the background, but what McGill is pressing harder is how that cashes out in the economic or ad extra life of the Son as given and revealed in Jesus Christ. This has lots of spiritual implications, but we will have to detail those later:

Now, the Gospel of John is totally preoccupied with the themes of glory, of fulfilled life, and of realized worship. John identifies these themes with the death of Jesus. However, the death of Jesus can only be understood when we know who Jesus is. The first part of John’s Gospel concentrates on showing us who Jesus is; the second part focuses on the significance of Jesus’ dying. John sums up everything that can be said about the identity of Jesus in the phrase, he is “from the Father.” He not only comes from the Father in a sequential sense. All that he has and is comes from the Father. The Father gives the Son of Man his knowledge, his purposes in will, his authority in judgment, and above all, his life. The Son has life in himself, not from himself, but from the Father. Yet, from the Father, the Son has life, life within himself. In all of this, John presents Jesus as living by what I have called an ecstatic identity—a being not by virtue of anything that is his own, but a being by virtue of what the Father continually communicates to him.[1]
