Here is an excerpt from a N.Y. Times column that captures a truth that we Christians knew or should have known all along, a nugget of truth where we might least expect it. It's a column about marital troubles. Here is an excerpt:
The truth feels like the biggest sucker-punch of them all: it’s not a spouse or land or a job or money that brings us happiness. Those achievements, those relationships, can enhance our happiness, yes, but happiness has to start from within. Relying on any other equation can be lethal.
This insight reminds me of something I recall seeing recently on the cover of a Catholic CD (my paraphrase): there is a vacancy within us that only God can fill.
