Scripture doesn’t tell us a lot about Jesus’ early life, when God became a human baby. The story at the beginning of his life will form the whole rest of the story.
It turns out that what it means to be God is actually what it means to be perfectly human, to love without a limit of reason; for Jesus’ whole being to be in solidarity with others.
And so we see the Incarnation as this invitation: we are invited to get into God’s stuff. We are invited into a perfectly human life, just as Jesus was perfectly human–to love beyond what makes sense. And to be fully human means that we also put our lives among the most wretched around us, refusing all the good reasons we come up with for cutting ourselves off and putting ourselves out of the way.
