A few people asked about notes from the recent two-part series called, "Who's Asking?" Which addressed the issue of God-ordained slaughter in scripture from both the skeptic's and the believer's point of view. Below are links to the sermon notes. These are just my unedited notes, but if you're seeking to refresh your memory with the Bible passages and reasoning from the series, they should do the job.
I should note here that almost nothing here is original to me. Many other scholars and students of scripture have addressed these questions. Much of the reasoning is taken from podcasts by Ravi Zacharias, some from William Lane Craig, and bits and pieces from other articles online.
