Towards the end of our time together, I asked Bill to explain why he wore clothes. Again I wanted to show he had no moral basis for his worldview, but it was just subjective opinion. I then used Genesis’ account of the origin of clothing to explain the gospel to Bill. God gave Adam and Eve clothes because of sin. The first blood sacrifice was a covering for our sin, a picture of Jesus Christ, the Lamb of God who takes away the sin of the world.
