They couldn't bring him to Jesus because of the crowd, so they dug a hole through the roof above his head. Then they lowered the man on his mat, right down in front of Jesus. Mark 2:4
The design is of 4 people looking over the hole in the roof downward at their friend. The rectangle in the center represents the mat with the middle circle representing the paralyzed man. As we think of the faith all five people have it is an incredible reminder of how important it is to have good friends!
