This past weekend I attended an apologetics conference hosted by Mt. Airy Bible Church. One of the speakers was Alan Shlemon of Stand to Reason. His talk was entitled, "Homosexuality: Truth and Compassion." Simply put, Shlemon's talk was the best I've heard from a Christian apologist on the topic and I told him so afterward.
In the video above, Alan answers the question, "Are people born gay?" and also provides some resources for those who want to learn more.
I also would want recommend Alan's article Homosexuality: Know the Truth, Speak It with Compassion. You can find it here.
Finally, Truthbomb team member Chase Deener has highly recommended Shlemon's small book The Ambassador's Guide to Understanding Homosexuality.
Courage and Godspeed,
