Every building is built to accommodate someone or something. If you are like me, when you drive by a new construction site you look for signs of who might be moving in. Will it be a store, a bank, a business, or someone’s home? We want to know who will dwell in that new building. Well, what we learn in the Christmas story is that our humanity was built to house the Creator and Lord of heaven and earth. The true temple of God is humanity. God the Son moves into his temple, his house, his palace when he unites himself to our humanity in the womb of the virgin Mary. The Father and Spirit construct a glorious house for the Son to dwell in. And God the Son has no "problem" uniting himself with us and dwelling with us as a man because we have been created for this very purpose.
