Such is the potential complexity, the combination of things natural and divine, of things gracious and owed, that Christians might identify in any particular instance of enduring the objectionable differences of another. When this potential complexity is actual, the conceptual depth of that endurance is greater and the reasons to love more substantial than the depth and substance of that same act when it is produced either by natural forbearance alone, or by the singular grace of divine forbearance. The former emerges from but one kind of temporal relationship, one kind of love, one collection of gifts and requirements.
