When Jesus created all things, He designed each thing with a specific purpose. Though she references an evolutionary process, this is a fascinating TED talk by Biologist, Dr. Diane Kelly on the structure of the penis and how it is absolutely unique in the world of biology. Spend a few minutes to watch this talk on the amazing penis, and share it with your friends (at least those who wouldn’t freak out about it.)
As Christians, rather than consider the male sexual anatomy (or any other body part for that matter), the result of random mutations, we choose to see this as more evidence of a loving Creator who had plans in mind and designed biological systems to carry out those plans perfectly. We already thank God for great married sex. Now we can even praise Him for the specific designs of the parts of our anatomies made for this purpose, including the amazing penis.
