Simon helps to understand how God sees us when we come to Him through the once & for all sacrifice of Jesus upon the Cross.  Our sin, that separates us from God is covered by the blood of Christ & we are washed clean by it’s cleansing flow. Using the illustration of a wooden cross with the names of everyone at the Good Friday service attached to it, Simon covers it with Red Crepe Paper to show that when we give our lives to Jesus, we are no longer held accountable for our sin – the debt is covered by the blood of Jesus.  That’s why it’s called “GOOD” Friday.
