I think you mean randomness in mutation: natural selection is anything but random (it’s a process whereby certain variants in a population reproduce more successfully than others). Evolution has a random component (mutations arise that may be detrimental, neutral or beneficial) and an emphatically non-random component (the different variants within a population do not all reproduce at the same frequency, meaning that the next generation will not be exactly like the previous one). So, as a whole, evolution is not random since it has a strongly non-random component. Evolution is actually remarkably good at producing similar results over and over again: consider how similar ichthyosaurs (descended from terrestrial reptiles) and dolphins (descended from terrestrial mammals) are. That’s the non-randomness of evolution at work. Some evolutionary creationists have argued that this non-randomness of evolution is a way that God uses evolution to shape His creation (the best work on this topic is Life’s Solution by noted Cambrian paleontologist Simon Conway Morris).

4. From HMV: I agree with you that the evidence seems to point to evolution being true. I've read Biologos and the old Evolution and Evangelicals blog. I've read books where people try to rework theology in light of this scientific knowledge. And yet, I'm left feeling confused and unsatisfied about doctrines like sin, the Fall, salvation, etc. What about you--have you found a satisfying way to maintain your evangelical theology in light of evolution?

This is a tricky question, because it hinges on the inherently subjective term “satisfying.” What I might find satisfying you might not – and in order to answer the question I have to guess at what you mean by it.

Personally, the concept of Divine accommodation has been helpful to me. This is a theology that has a long heritage in Protestant circles (e.g. Calvin). In a nutshell, it’s the idea that God, in his grace, brings himself down to the level of the audience he is communicating with. For Genesis, that audience is an ancient near-eastern culture, not our modern scientific one. For Genesis, my view is that God wants to communicate that he is the Creator of all that there is, that he has given humanity a special image-bearing role within it, but our sinfulness has broken that relationship, et cetera – but that he doesn’t see a need to give them a science lesson first. I would recommend Denis Lamoureux’s book I Love Jesus and I Accept Evolutionand, though not directly related to science, Peter Enns’ book Incarnation and Inspiration may also be helpful to you (it certainly was to me).

5. From Chris: From the perspective of an evolutionary creationist, what meaning and value do you extract from the creation accounts in Genesis and why would they be important for the Christian faith if they can't be taken literally?

See the answer above – I see the Genesis narratives as God graciously reaching down to an ancient culture in order to communicate to them that he is their creator, that they are alienated from him, and that he desires that they be restored to fellowship through his offer of covenant with him (ultimately pointing to the need for God to step into history himself as the One who can keep the covenant on our behalf).

6. From Paige: I'll never forget sitting in one of Dr. Charlie Liebert’s classes several years ago and hearing him ask the question: "What came first, death or sin?" If we believe that there was no death before sin, it causes a wrinkle in our ability to hold to the theory of evolution. As a scientist, this question caused him to reexamine the evidence. How have you personally dealt with this "wrinkle?"

Yes, if you believe that no death of any kind (plant, animal, bacterial) occurred before human sinfulness, then this precludes an evolutionary view, since the fossil record is (obviously) a record of things, well, dying. If you hold that no human death came before sinfulness, then it depends on what you call human (there is a gradation of forms leading up to the modern human skeleton in the fossil record, as well as the overwhelming genetic evidence that we arose through an evolutionary process) and what you consider sin (i.e. when did we become accountable to God for our actions?). There is also the long-standing observation that God decrees that Adam and Eve will surely die the day they eat of the fruit – and then they live for several hundred years after the fact. I’d also recommend reading through Romans 5:12 – 8:17 (which, as you know, is all about Adam, sin and Christ as the second Adam) and making a mental checklist of how Paul uses the term death in this passage. References to physical human death are in the minority – suggesting that Paul’s understanding of what is going on in Genesis has a lot more nuance than a simple literal reading would imply.

7. From Jane (from her husband, an atheist): All of the questions posted so far approach the topic from the viewpoint of assuming belief in a god. As an atheist, I don’t share that assumption. (For those who might not appreciate it, evolution offers a mechanism for understanding the existence of living organisms that doesn’t require the existence of a god.) If you transitioned from an anti-evolutionary/pro-intelligent design view to an evolutionary creationist view a few years ago,” why didn’t you keep going and just embrace evolution and drop the theistic aspect?
