"Most sermons sound to me like commercials - but I can't make out whether God is the Sponsor or the Product"

This quote by Mignon McLaughlin is a commentary en route that lots of sermons are delivered. She is recommending that many preachings sound like commercials, where the speaker is trying to offer something. She is questioning whether God is the sponsor of the preaching, or the product being sold. This could be interpreted as a criticism of the way that some spiritual leaders utilize their preachings to promote their own agendas, instead of focusing on the mentors of God. It could also be analyzed as a criticism of the way that some religious leaders utilize their sermons to manipulate their parishes into following their own beliefs. Ultimately, McLaughlin is recommending that lots of sermons lack the spiritual depth and credibility that need to exist in a sermon.
