Here are couple links to things that were referred to in last week's sermon:
First, I highly recommend Russell Moore's book, Tempted and Tried. I am not aware of a book on temptation that is easy to read, honest about our depravity and hopeful because of the victory of Jesus.

Second, here is the video clip of the baby iguanas fleeing countless racer snakes. If you have an irrational fear of snakes, don't watch this alone!
