Experimental Theology: George MacDonald: The Real Emerald City
Sometimes metaphors to describe our experience of God and our relationship with God fall short. At some point they will break down. They are a pale reflection of knowing the true and living God, author of the universe.
The idea of God seeing us 'through rose-coloured glasses' does not stand up to scrutiny from the perspective of inner transformation rather than a cosmetic cover-up of sin.
This made me think (plus I do love a good 'Wizard of Oz" illustration).
