The Created Order as Sacrament by Henri Nouwen
When God took on flesh in Jesus Christ, the uncreated and the created, the eternal and the temporal, the divine and the human became united. This unity meant that all that is mortal now points to the immortal, all that is finite now points to the infinite. In and through Jesus all creation has become like a splendid veil, through which the face of God is revealed to us.
This is called the sacramental quality of the created order. All that is is sacred because all that is speaks of God's redeeming love. Seas and winds, mountains and trees, sun, moon, and stars, and all the animals and people have become sacred windows offering us glimpses of God.
