“What I mean, brothers, is that the time is short. From now on those who have wives should live as if they had none; those who mourn, as if they did not; those who are happy, as if they were not; those who buy something, as if it were not theirs to keep; those who use the things of the world, as if not engrossed in them. For this world in its present form is passing away.” (1 Cor 7:29-31)

Paul isn’t afraid to lump marriage in with things that will pass away and therefore things we shouldn’t hold on to as if they were ours to keep.  The healthiest marriages (or any other kind of relationship) will be the ones in which neither person makes undue claims to ownership.  The having and the holding of our marriage vows are not having titles or holding death grips, they are having faithfulness and holding in earnest for the true owner.
