In my opinion, one of the most pressing worldview/apologetic questions of the day is what makes a human valuable? After all, we live in a day when so many people fight for human rights, equality, and value. It certainly comes up in every election. But why do humans value each other so much? What is abut humans that compel us to defend their rights and dignity?
Also, here is a lecture by Angus J.L. Menuge, where he compares naturalism and theism and which worldview can adequately ground human rights. In your conversations with others, talk to them about this issue. It is a great conversations starter.
