The Thinking Christian's "The Child Sacrifice Question" - Counter apologetics

I have commented before on Tom Gilson's website, The Thinking Christian. He writes well, even if I disagree with the content of his work.

Up until this point, I have had no problem posting comments, but now things appear to be somewhat... clunky? So I have decided to post a full response here.

Tom's latest post is an apologia for God's testing of Abraham, by asking him to sacrifice his first-born child. Of course, I have some issues with his appraisal of the situation.

He begins by asking, "What is it about a command to sacrifice a child that makes it wrong?"
