Consider the Incarnation of Christ and the paradoxes that His coming contain. In order to save the sinful, fallen creatures of His creation God choose to become one of them. In order for man to gain eternal life Christ had to lose His life. He was born of a Virgin, entering the world not as the Power of the Universe, but as the weakest of weakest, a tiny infant, who needed to be clothed, fed,and kept warm. The Creator all things, responsible for all matter, cannot find a simple room to be born in and stay the night. He ends up in a stable shivering in the cold night air, while Caesar slept in the palace, cozy and warm. Jesus, the bread of Life, who feeds the world is placed in a trough, where the animals eat from.
"The true light, which enlightens everyone, was coming into the world.He was in the world, and the world came to be through him, but the world did not know him. He came to what was his own, but his own people did not accept him."
There are many more paradoxes about Christ and His message of hope but I would like to end with this; if you really think about it; life is really Advent and Advent is really life. Our hearts are always waiting for Christ, always preparing a room for Him. It is in living a life of holiness that we anticipate Him coming, make straight the path for Him.
