Imagine a Mother sitting and watching her one year old baby at play.
From the perspective of any observer other than the Mother, the actions of that child are highly imperfect - pooping, weeing, vomiting, being selfish, banging and breaking and tearing stuff...
But from the Mother's perspective that child's behaviour is perfect; because he is doing just what a child ought to do, needs to do - it is a child who is growing, developing, learning - precisely as the Mother wished and hoped and planned.
So, from the perspective of his Mother, that baby is not meant to be perfect in terms of his specific current behaviours, he is not designed to be - he cannot possibly be - perfect in that sense.
But the baby is - and is meant to be - perfect in terms of being on a trajectory of learning.
"Mother" = God
"Baby" = Mortal Men on earth
"Growing, developing and learning" = Theosis.
The metaphor derives from William Arkle - 56.00 minutes
