God is love, and all his operations proceed from love. Once he wills to manifest that goodness by sharing his love outside himself, then the Incarnation becomes the supreme manifestation of his goodness and love and glory. So, Christ was intended before all other creatures and for his own sake. For him all things were created and to him all things must be subject, and God loves all creatures in and because of Christ. Christ is the first-born of every creature, and the whole of humanity as well as the created world finds its foundation and meaning in him. Moreover, this would have been the case even if Adam had not sinned.
-- Saint Lawrence of Brindisi
