God's great gift of grace
John Barclay contends that there six different "perfections" of grace-- six distinct ways in which "grace as gift works itself out toward extremes or its farthest point in meaning and implication."
-superabundance: the supreme scale, lavishness, or permanence of the gift;
-singularity: the attitude of the giver as marked solely and purely by benevolence;
-priority: the timing of the gift before the recipient's initiative;
-incongruity: the distribution of the gift without regard to the worth of the recipient;
-efficacy: the impact of the gift on the nature or agency of the recipient;
-non-circularity: the escape of the gift from an ongoing cycle of reciprocity.
