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
I read this quote and it struck a chord in me. Christianity, of course, quoted in this case isn't the religion itself but rather the influence of Christ, i.e., His gospel.
Think about this for a sec. At night we can hardly see, even with an artificial light source. Our vision is tunneled to the extent of the light source's reach, if we have one available.
Then....the sun rises and, because of the sun, we don't need artificial light any longer for we can see everything around us. And not just immediately around us, but everything is now visible, our vision isn't tunneled any longer.
Christ and His gospel allows us to see everything. We are no longer blinded by darkness or tunneled to only a limited view, but we see everything. His gospel illuminates everything.
I know the difference that I feel when my vision is limited at night or in darkness vs during the sunlight. I feel more apprehensive, anxious, and unsure of myself when I can't see beyond the reach of a light source. But the light that Jesus Christ gives, has no limits. His reach is limitless and penetrates every corner and crevice.
I know by which light I'd prefer to walk in this life.
