Several weeks back, I finished my series on The Chronicles of Narnia, and now I am thoroughly enjoying reading through Paul Ford’s Companion To Narnia: Revised and Expanded. It is basically a reference work that discusses the process of C.S. Lewis writing the Chronicles, analyzes how they relate to the rest of his works, and provides encyclopedic entries for everything imaginable in the world of Narnia. I am just now in the Es, so I have a long way to go, but it has been a lot of fun to read.
A while back I read through the entry for Aslan, which, as you might expect, is incredibly lengthy, with the Great Lion being the central character of the Narnia series and Lewis’s imagined Christ Figure in the world of Narnia. In that entry, Ford makes an insightful comment on Lewis’s effort to point his readers to the implications of the incarnation:
[Aslan’s] encouragement of the now-revived lion with the phrase “us-lions” and his employment of the giant to break down the castle walls and the sheepdog to organize the creatures into a force that will be helpful in what will later be called the First Battle of Beruna are all instances of Lewis’s profound belief that one of the consequences of the incarnation (God’s desire to identify with us by becoming one of us) is that he wants our help in the process of transforming the world.
In the Incarnation, God identifies Himself with humanity through Jesus of Nazareth entering the world stage in the form of a baby. In so doing, God affirms the goodness of creation and also His intention to partner with humanity in bringing about His purposes for that creation.
This is, in large part, what it means to be created in God’s Image; we are God’s representatives, bearing His authority to carry out the task He has given us. This is the picture we have of Adam and Eve in the garden: God giving them the task to steward and cultivate His creation, partnering with Him, under His authority, to take care of it and develop it.
Tragically, Adam and Eve fail to live up to their vocation. In the bitterest of ironies, they clutch after the forbidden fruit hoping to become like God, failing to realize that they already were! And humans have similarly failed ever since then.
In the Incarnation, Jesus comes to show us a different way. He perfectly reflects the divine image, obeying the Father’s will in all things. Rather than seeking after power or God-likeness, He willingly lays it down and lives as a servant, even to the point of dying on the cross.
Those of us who would follow Jesus are called to imitate His example. The vocation that God bestowed upon humanity in the garden has not changed: still, we are encouraged to take up our crosses and join in God’s mission. In The Lion, the Witch and the Wardrobe, the resurrected Aslan could have defeated all evil, established his reign and rule, and brought about the transformation of the world all on his own, but he chose not to. And this, as Ford points out, is no accident: Lewis was simply reflecting the biblical teaching that the all-powerful God chooses to bring about the redemption of all things in collaboration with human agents of new creation.
One of the great truths of the incarnation is that God wants our help in the process of transforming the world.
