Marriage is a call to die [to self]… Christian marriage vows are the inception of a lifelong practice of death, of giving over not only all you have, but all you are. Is this a grim gallows call? Not at all! It is no more grim than dying to self and following Christ. In fact, those who lovingly die for their [spouses] are those who know the most joy, have the most fulfilling marriages, and experience the most love.
