Cornerstone Sermon Podcast carries the preaching of the Cornerstone group at Grace Community Church. The convictions behind it are stated plainly from the front: the Bible is inspired, inerrant, authoritative and sufficient, and the church has long committed itself to expository preaching. That commitment shapes everything else in the feed. Most recent episodes stay in Ephesians, in the household passages that close chapter 5 and open chapter 6. Wives, husbands, children and parents each get their turn. The preachers rotate, and they refer to each other's sermons, which makes the run feel like shared work rather than one voice. One speaker warns against pulling a single verse out of Paul's letters, whether it is about the armor of God or about wives and husbands, and asks what the whole letter is arguing. Another sets marriage in a larger frame: it is meant to picture Christ and the church, and because every relationship contends with sin, a marriage that shows grace points beyond itself. A sermon on husbands opens with a prayer that the congregation will do more than study the text in an academic way and will instead be changed by it. The parenting message is the sharpest in tone. Reading from Ephesians 6, its speaker addresses children, parents and grandparents together, then argues that the culture, especially in California, is undermining a parent's God-given authority to require obedience and to teach, train and discipline. The advice is to deepen conviction rather than retreat. The speaker also ties the home back to the marriage, warning that an unbiblical relationship between a mother and father can leave the parents distracted by it. The sermon closes with a prayer that the children in the room will be a blessing to the church and a light in a dark world. Not every episode is a sermon. In one, a Q&A panel brings three couples to the front, Mark and Lisa Tatlock, Brendan and Cheryl Bates, and David and Lynn Phillips, to talk about how they have been applying Scripture in their own lives, sharing microphones as they go. The purpose is practical: Bible application, and learning from one another. In another, a missionary couple who met in Sylmar at fourteen share highlights of their ministry instead of preaching, noting that the congregation already gets plenty of solid preaching. Their family rundown, with seven children and a grandchild count that needs a quick correction, is one of the lighter moments here. What a listener gets is one congregation's Sunday teaching on marriage and parenting, delivered with conviction and set within the flow of a single book. The speakers talk directly to their own congregation and speak plainly about authority in the home.
