A love affair has to do with immediate personal satisfaction. But marriage is an ordeal; it means yielding, time and again. That’s why it’s a sacrament: you give up your personal simplicity to participate in a relationship. And when you’re giving, you’re not giving to the other person: you’re giving to the relationship. And if you realize you are in the relationship just as the other person is, then it becomes life building, a life fostering and enriching experience, not an impoverishment because you’re giving to somebody else … This is the challenge of a marriage.
