For a bit of the flavor of Tripp's DVD on parenting, here is an article just posted at The Gospel Coalition website. He writes:
You and I must remember that our Lord loves our children more than we ever could, and his commitment to their growth and change is more faithful and persevering than ours could ever be. Because of this, in his grace and love, he will manufacture moments that expose the needy hearts of our children to us. He will faithfully employ the little moments of everyday life to expose to us and our children their need of rescuing and forgiving grace. And he will not do this only at the moments that you feel are appropriate and when you feel most prepared.
Read the rest; if you're a parent, it's well worth your time!
