Here is the lesson from May 2nd, 2010.  He discussed how our view of God also effects our view of love and justice.  Without the cross we cannot fully understanding these two concepts.  The greatest love that we have ever seen is at the cross, God becoming a man and dying the death we should have died.  Also at the cross we see perfect justice, Jesus worthy to be our substitute, taking on our sin, and then that sin being fully paid for.  Here is the link to the lesson.
