The NASA museum once hosted a group of blind people to discuss how they could make their exhibits more accessible – particularly the famous aircraft that hang from the ceiling. The director asked if a scale of model of each aircraft that they could touch would be helpful. They thought it was a great idea, but only if it was placed directly under the real thing. What they were saying is that touching the representation of each great aircraft would only touch their hearts and minds if they also knew they were in the presence of the original, which they were unable to see or touch.
That’s why it is that, though we cannot see God, when we do see and touch love we know we are in God’s presence. The Bible says: ‘Noone has seen God. But if we love one another, God dwells deeply within us.’
