Here is an excerpt from Robert Barron’s Catholicism that I have always loved! He says that the incarnation means that God is non-competitive with his creation. And actually, the closer the divine life gets to us, the more alive we are:
The incarnation tells us central truths concerning God and us. If God became human without ceasing to be God and without compromising the integrity of the creature the he became, God must not be a competitor with his creation. In many ancient myths and legends, divine figures such as Zeus or Dionysus enter into human affairs only through aggression, destroying or wounding that which they invade… But there is none of this in the Christian doctrine of the incarnation. The Word does indeed become human, but nothing of the human is destroyed in the process; God does indeed enter into his creation, but the world is thereby enhanced and elevated. The God of the incarnation is not a competitive supreme being but rather, in the words of Thomas Aquinas, the sheer act of being itself, that which grounds and sustains all of creation, the way a singer sustains a song.
And the incarnation tells us the most important truth about ourselves: we are destined for divinization. The church fathers never tired of repeating this phrase as a sort of summary for the Christian belief: Dues fit homo ut homo fieret Deus (God became human so that humans might become God). God condescended to enter into flesh so that our flesh might partake of the divine life, that we might participate in the love that holds the Father, Son and Holy Spirit in communion. And this is why Christianity is the greatest humanism that has ever appeared (p 1-2)
