God is not an idea. Christian faith is not a set of propositions you either believe or reject. According to a proper Trinitarian understanding, God is essentially relationship, a relationship of sheer, active, ecstatic, self-giving love.
This 51% Christian moniker is a ridiculous label with a deadly serious point. You now have permission to doubt, to question, to get angry at God. But, in the end, its not about you. Faith is about relationship: a living, daily relationship, based on trust, and active in concrete, daily practices.
