I believe this thesis. I don’t expect agnostics and humanists to, though. Still, I believe the statement is true, even for them. Consider my explanation below.
What Lewis is saying is that God is the Source of all good. In the Scriptures, in fact, some of the attributes of God can be viewed as so intimately a part of his divine nature that the particular virtue is, in its purity, a facet of the Lord’s identity. Thus God the Father and God the Son are said to truly be: Love, Light, and Truth.
Christians are inclined to attribute any good fruit we see as coming from the Source of good. Thus, when secularists do something inarguably good or altruistic, we have no problem attributing its inspiration to God. Yes, they may see through the glass dimly, and may for example recognize only the beauty of nature or the magnificence of the cosmos. But these are God’s handiwork, and so we return to where we began.
It is actually the second portion of this quotation that most intrigues me. “Everything else is . . . bad when it turns from Him.”
I suppose I can illustrate this truth more effectively than I can explain it.
Patriotism is a good thing. It results in cohesive communities where individuals are willing to make sacrifices on behalf of their fellow citizens. Focus is on the common welfare. However, run amuck, patriotism can become a deformed thing. The Third Reich united and inspired a weak and demoralized nation, but at a bloody price.
Love of Family is a good thing. Most of us experience the joy of this fact. However, carried to obsessive bounds, it can result in horrendous acts. Not a week passes without the news relaying accounts of parents murdering their own children in the face of a divorce, incarceration or some other form of separation. In their depraved minds, the thought of not being together warped into something uglier than death itself.
Human Freedom is a good thing. If that weren’t so, God wouldn’t have created us with free will. It allows human to say “yes” to him and live in a relationship with our Creator as his children rather than as mindless automata. But, apart from God, is there any question that this most wonderful gift becomes a curse? Proof overflows from the pages of our newspapers.
So, Lewis reminds us that the things of this world possess no intrinsic good. When things such as generosity, courage, and creativity are imbued with a divine element, only then do they become capable of being truly good.
The strongest challenge to this belief comes in the notion that even those who do not acknowledge God are capable of doing things we all consider “good.” As I said above, Christians have no problem celebrating selfless acts of their unbelieving neighbors. The reason for this is actually quite simple. Even though secular humanitarian efforts do not look to God, since they are altruistic, they consciously look away from self. In other words, they are not intentionally turning away from God, but, ignorant of his presence, they still transcend selfish or carnal interests. And, insofar as they are free of these sinful considerations, they possess the capacity for actions rightly deemed “good.”
Ultimately I believe this is due to the truth that all women and men are created in the image of our God. Whether we acknowledge it or not, the echoes of that truth resound throughout our being.
