1 John 3:1-3
"See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him. Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is."
The present and future identity: we are children of God now (tekna theou esmen). The future: we shall be like Christ (homoioi auto esometha) when we see him as he is. The vision of Christ will transform us into his image — glorification as contemplation.
