He explains why he is a Christian and why he is "more than his genes" in Am I more than my genes? Faith, identity, and DNA.
Here's the opening paragraph ...
The word “genome” suggests to many that our DNA is simply a collection of genes from end-to-end, like books on a bookshelf. But it turns out that large regions of our DNA do not encode genes. Some once called these regions “junk DNA.” But this was a mistake. More recently, they have been referred to as the “dark matter” of our genome. But what was once dark is slowly coming to light, and what was once junk is being revealed as treasure. The genome is filled with what we call “control elements” that act like switches or rheostats, dialing the activation of nearby genes up and down based on whatever is needed in a particular cell. An increasing number of devastating complex diseases, such as cancer, diabetes, and heart disease, can often be traced back, in part, to these rheostats not working properly.
