Holiness is a Process

This isn't mod "process theology," just the reality attested by Orthodoxy from the beginning that the Uncreated is infinitely greater than creatures, so we'll never 'arrive' at being 'all that we can be,' we'll just keep trying to be holier in this life, and even in the next go "from glory to glory." As St. Vladimir's Seminary professor Peter Bouteneff puts it (emphasis added):

'Sanctity is God’s will for everyone, and it is our clear and definite vocation as faithful members of the Church. Sanctity is also not a simple “yes or no” proposition. Done right, the very pursuit of sanctity is sanctity. It is a journey without arrival, and our failures on the way must not be cause for despair, but for change and renewal.'
