I believe in Christianity as I believe that the sun has risen: not only because I see it, but because by it I see everything else.
C. S. Lewis, "Is Theology Poetry", The Weight of Glory, November 1941
As I sit and ponder this quote, I equate the sun to not just Christianity but to Christ Himself. Christ is the Light of the world. Christ illuminates everything. Granted, His light is far brighter and more illuminating than the mere sun. But, the sun is used as the example, or another light in darkness, because mortal minds can comprehend it as the closest thing that illuminates everything.
For me, when I look at the world under the light of the sun, I think I can see everything that my eyes can focus on. But is that everything that the sun is illuminating? Or is that only what my lens is showing me? Hence, my view is limited.
Then I think of the light of Christ and everything that He illuminates. When I look through my spiritual lens and see the gospel and the truth therein, is that everything that He illuminates? Or, is that only what my limited spiritual sight can see? Yet in this part of the Plan, my view is still limited.
We know two things for certain. One, is that as we focus more on the central example in our view, which is Christ, then our lens through which we see the gospel and truth will expand and grow larger so that we can see more. So our view becomes less limited. And yet, Christ still remains in the center.
And, two, because His light shines on everything, and I mean everything (because His reach is endless, limitless), our ability to view everything opens to our sight as we see with our spiritual eyes and less with our physical ones. It has always been there, but now we can see it. I equate that to being able to see all sides of a mountain, or anything for that matter, at the same time, when all you can see, right now, is the one side in front of you but can't see around to the backside. With Christ, I will be able to see all sides at the same time. How?, I don't have a clue. I just know I'll be able to.....if I "look to Him and live".
