Why does sin exist?  God created all things, and nothing was created without Him.  So, why does sin exist?  Some Christians say that sin is a byproduct of God giving us free will.  Why did He give us free will?  The Christian response – God gave us free will so that we would freely choose to love Him.  My response to this – why couldn’t God give us free will, so that we could freely choose to love Him, without allowing sin to exist?
