"It is the fact of God's Trinity which requires that his concluding gift to us, should he make one, must be inclusion in his own life, the gift not of something other than God but of 'all he is' [Luther]. The triune God does not and indeed cannot beneficently affect us causally; for him, causal action, with its intrinsic distancing, would mean exclusion from himself and so cursing rather than blessing. The goal of all the biblical God's ways is the glory of God. Were an otherwise biblical God -- contrary of course to possibility -- monadic, his intention of his own glory would be a sort of omnipotent egocentricity, and the reality of God would be a universal moral disaster. But God's glorification of himself is instead supreme blessing because the triune God can and does include creatures in that glory."
