Now Russell Moore in his book Adopted for Life addresses the same subject and I will quote him.
"One area of needed reformation in our preaching is in wedding sermons. Too many of our weddings, even in the most conservative churches, pretend as though the event is about the formation of a 'couple.' The language of older wedding ceremonies, which mention procreation and the children of the union, seem quaint and antiquarian to our ears. We're the ones who are odd, however, not our forebears. Marriage is about the formation of a new family. What would happen if our wedding ceremonies were less about a 'celebration of the love of Joni and Todd' and more about the formation of a new covenant family? What if the officiating pastor spoke to the couple not only about what it means to be a faithful husband and wife but what it will mean to be a faithful father and mother? What if every wedding ceremony included a prayer for the children of the union, that such children might actually be and that they'd be saved at an early age? What if this prayer included the mention of such children as coming either through birth or through adoption? Such small measures could help refocus our minds and hearts on our responsibilities to the next generation."
