The subject of ethics is one that we cannot afford to be ignorant on. There are some good Christian resources but we should be aware of what non-Christians are saying as well. I have been listening to a series of podcasts called Bio-Ethics Bites. This series is connected with Oxford University. It includes an interview with controversial philosopher Peter Singer. What I have heard is disturbing and it makes me want to deepen my knowledge of ethics. The first step is being aware. You can also find these podcasts on iTunes here.
