3. On God in Nature

God is revealed in nature! The bible says so (Romans 1.20) and you don’t even have to be a Creationist to see it – the evidence is there in plain sight.

But to suggest that, because aspects of nature are beautiful (or stunning or endearing) from a human perspective, the natural world can only have come from the hand of a loving Creator is merely to argue from a position of incredulity: “I can’t conceive how such beauty came to be; it must have been God.”

I live close to the countryside and although there is much that is impressively beautiful, the mercilessly cruel working of nature is also apparent: ruthless competition, even between plants and certainly among animal wildlife; waste on a vast scale; predation – young blue-tit (chickadee) chicks in my garden eaten a few weeks ago by magpies – death and sex.

The incredulous believer who refuses to see these aspects of nature and sees only beauty – and much of it is undeniably beautiful – is being disingenuous in their selection of evidence (confirmation bias in action). If God reveals himself in nature, then just as it is, he has to be callous, cruel and indifferent to suffering too.

“Ah, yes,” says the Christian, “but that’s because we live in a fallen world,” which is having it both ways: God is apparent in nature, except when he isn’t… because then it’s a fallen world.

Speaking of which –


4. On This Being a Fallen World

Creationists, such as those at Answers In Genesis, like to argue that genetic mutations in humans and animals fail to ‘increase the information’ and, further, that such errors would only lead to malfunction and the death of the organism. They’re right about the latter; significant mutation is almost always detrimental. However, according to Nature, ‘others have little or no detrimental effect. And sometimes, although very rarely, the change in DNA sequence may even turn out to be beneficial to the organism.’ A mutation that increases the chances an animal will survive and reproduce ensures that the particular mutation is passed on to its offspring.

The constant shuffling and recombining of genes in sexual reproduction also changes and ‘increases the information’ within the genome with the consequent effect on the phenotype (the genome’s physical expression). This is analogous with the twenty-six letters of the English alphabet producing new, unique sentences, paragraphs and texts every time they are recombined.

Creationists are wrong therefore to insist that mechanisms do not exist to change or add to genetic ‘information’. They are wrong too that variations caused by mutation cannot contribute to the evolution of an organism; while most born with such variance are likely to die before they can reproduce (natural selection in action) a minority are able to pass on the changes. Mutation and sexual recombination of genes are integral to evolution and the development of the organism.

I mention this because the bible presents quite a different scenario. In Genesis, the world and everything in it is created in a state of perfection. Then, because of human disobedience and sin, God feels compelled to curse his entire creation and the sudden or gradual – Christians are none to clear about which it is – transition to degradation, entropy and death begins.

It’s here that creationists’ objection to the role of mutation in evolution proves a stumbling block for their own scenario: a system designed to function in a particular way cannot continue to operate effectively after undergoing such a radical, brutal overhaul. We know of no other system that, having undergone such demolition, can continue to work in the way it was intended to, and certainly not as effectively as the ecosystem has for millennia. Look, for example, at how human activity has contributed recently to radical changes in climate.

Nature relies on those things that Christians say arose because of God’s curse on it: death, disease, waste, competition, cruelty. A system with such inherent ‘faults’, so far removed from how it was ‘designed’ to operate, would have failed long ago.

From this we can conclude that:

Nature/ecosystems/life were not ‘designed’ at all.

     They were never part of a ‘perfect’ creation.

         They were not cursed and are not now faulty components of a fallen,     malfunctioning world – nor could they be.

                       They could not operate any differently from the way they do.

                             They will not, despite what the bible says (Romans 8.20-21), be restored one day to a state of perfection they didn’t have in the first place.
