Jen and I are going through Everyday Talk by John A. Younts. "The most powerful influence in your child's life is everyday talk," Younts writes, and of course he establishes this by appealing to Deut. 6. So far the book has been helpful, encouraging and convicting, as he points the reader toward a more Gospel-centric approach to casual conversation with your children based on your own interactions with the word of God. Definitely worth reading and discussing with your spouse.
