Tim and Kathy Keller write: “In so many cases, when one person says to another, ‘I love you, but let’s not ruin it by getting married,’ that person really means, ‘I don’t love you enough to close off all my options. I don’t love you enough to give myself to you that thoroughly.’ To say, ‘I don’t need a piece of paper to love you’ is basically to say, ‘My love for you has not reached the marriage level.’”
