Compassion. Honesty. Friendship. Persistence. Faith. Everyone recognizes these traits as essentials of good character.

From the Bible to American history, from Greek mythology to English poetry, from fairy tales to modern fiction, these stories are a rich mine of moral literacy, a reliable moral reference point that will help anchor our children and ourselves in our culture, our history, and our traditions—the sources of the ideals by which we wish to live our lives.

    We worry that our students will be "behind," that they won't score well on the SAT, get into a good college, or read enough of the Great Books. Our souls are restless, anxiously wondering if something else out there might be just a little bit better—if maybe there is another way or another curriculum that might prove to be superior to what we are doing now. God doesn't call us to this work and then turn away to tend to other, more important matters. He promises to stay with us. He assures us that if we rely on Him alone, then He will provide all that we need. What that means on a practical level is that we have to stop fretting over every little detail. We need to stop comparing. We've got to drop the self-inflated view that we are the be-all-end-all of whether the education we are offering our students is going to be as successful as we hope it is. After all, our job is not to be successful—success itself is entirely beside the point. It's faithfulness that He wants. Teaching from Rest offers inspiration, insight, and practical help for the homeschooling mom. Take a deep breath homeschooling mama; He's got this.
