It has happened countless times in your life. You woke up and the grass was wet from the rain the night before, or so you thought. How do know the rain caused the wetness on the grass? Perhaps it is just a coincidence that the grass happened to get wet at the same time the raindrop hit the grass. What reason do you have to connect those two events in a cause and effect relationship? With this in mind, Dr. Sproul teaches us David Hume's challenge to the relationship of cause and effect, and how that affects Christian belief.
