Apparent Contradictions: God or Satan?

 First order of business, I apologize for my lack of updates lately.  I took a trip to California two weekends ago with family and was busy before and after prepping and catching up.  Now I'm back and hope to resume my normal Tuesday, Thursday, Friday routine.

You guys have voted in the next apparent contradiction for me to debunk today and it is the one found in the following verses.

Again the anger of the LORD was kindled against Israel, and he incited David against them, saying, "Go, number Israel and Judah."  -- 2 Samuel 24:1

Then Satan stood against Israel and incited David to number Israel.  --  1 Chronicles 21:1

Both of these passages are telling the story of the same exact event.  So the question is "Who incited David to number Israel?"  2 Samuel says that God did it.  1 Chronicles says that Satan did it.  Is the Bible calling God and Satan the same person?  Did the author of Samuel (likely Samuel) and the author of Chronicles (likely Ezra) disagree?  What's the deal?

Theology Thursday: Can Demons Hurt Us?

The votes are in and today's question is: Can demons hurt us?  Whether you're a Christian or not, you've probably been scared of demons at one point or another.  Have you seen the Exorcist?  Have you heard strange, scary, and unexplainable stories around a campfire?  The devil and demons can be a scary thing to talk about, but what is true and what is Hollywood?  What is real and what is hype?
