Another piece of great theology from Dr Who tonight: When two parallel worlds collided, the Doctor declared: "All the reflections have now become gateways."
Jesus came to earth to reveal God, in whose image we are all created. To see God, we can look at each other. And, when we look in the mirror, God, in infinite love, looks back at us, beloved children.
Heaven came to earth and we are afforded a glimpse of all that God, in love, bequeaths to us. God's gift of love is not something for which we must strive or work to attain - it is ours already.
Look in the mirror. Look at each other. And see God, even in the most distorted image - a gateway to heaven, here on earth.
