No but i wish they'd write one for the church as a 'love dare' to challenge them to love the world and those who are not of the faith yet/who the church is called to reach. I believe that we can implement these practices not only in our marriages/those of us who aer married..but in all areas of our life. We should be living 1 corinthians 13 on the daily, morning,noon, and night..step by step..day by day..action after action..loving..even when it hurts, even when you feel it may not produce a harvest..you don't know what will succeed and what won't..so cast your love upon the world..and let God do the rest!
