For my first post, I would like to recommend the convicting series on marriage preached by John Piper in Spring 2007 (actually, January to July).  When you’re in a planning frenzy, just listen to one of these sermons and your heart will put back in its right place, upon the glories of Christ.  Even though I’ve grown up ‘knowing’ that marriage reflects Christ and the church, this series thoroughly explain the purpose of marriage, the Biblical roles of a husband and wife, forgiveness, singleness, having children, and much more!
