“From this reference is it implied that we will be exactly like God the Father, Son and Spirit-at the same level?”
It means that we will be in the image and likeness of God. Here’s what +Gregory Palamas said:
“Three realities pertain to God: essence, energy, and the triad of divine hypostases. As we have seen, those privileged to be united to God so as to become one spirit with Him - as St. Paul said, ‘He who cleaves to the Lord is one spirit with Him’ (I Cor. 6:17) - are not united to God with respect to His essence, since all theologians testify that with respect to His essence God suffers no participation.
Moreover, the hypostatic union is fulfilled only in the case of the Logos, the God-man.
Thus those privileged to attain union with God are united to Him with respect to His energy; and the ‘spirit’, according to which they who cleave to God are one with Him, is and is called the uncreated energy of the Holy Spirit, but not the essence of God.”
See? Easy!
Well, no! Does this mean that God is like the Blob that sucks us up into some Godly creative energy mass?
