In other words in that Bethlehem stable, not only are people visiting Jesus, but God is visiting us. He no longer just speaks through the prophets. Now he steps onto the stage himself, and not just to visit, but to redeem.
An ancient nativity play has the child Jesus standing in the middle of the stage with an angel approaching him from either side. One angel offers him a gorgeous bouquet of roses, the other a crown of thorns. For a moment the child hesitates. He fingers the petals of the roses, enjoys their fragrance, and then with a tiny sigh, he takes the crown of thorns.
