Before God even created humanity he only wanted to be God sharing himself with us.  And he wanted us to be with him in the deepest union and communion. Indeed, who we are as humans is inseparable from who we are with him.

That eternal purpose became actual in Immanuel.  He is God with us sharing our humanity so that in him we might be with God sharing all the Son has with his Father in the Spirit. As Paul says our life is now hidden with Christ in God.  The Father’s unique Son has united himself to us in our humanity so that we might be united with him in the Spirit. And in that living union we are now with God.

You might react saying all that is just an ideal.  The reality is I live far from God and God seems far from me.  Nevertheless, the reality is Christ as God with us and we with God.  True, our daily lives often contradict this reality.  Even so, the reality is God has united himself with us in our humanity so that God really is with us.  And the Spirit of Christ has united us to Christ so that we are with God in him.  Furthermore, the indwelling Christ is now expressing his own life with God in and through us.  No matter how much our lives contradict the reality we know that God is with us and we are with God.  Let’s live in that reality in union with Christ by his Spirit so that the reality may come to daily realisation in us.
