Dr. Tim Kimmel, from his book, Grace - Based Parenting:
I'm urging you to raise your children the way God raises His. The primary word that defines how God deals with His children is grace. Grace does not exclude obedience, respect, boundaries, or discipline, but it does determine the climate in which these important parts of parenting are carried out. You may feel extremely inadequate and fragile in key areas of your life, but God comes alongside you in those very areas of weakness and carries you through with His grace. You may be frustrated, hurt, and even angry with God, but His grace allows you to candidly, confidently, and boldly approach his "throne of grace." His grace is there for you when you fail, when you fall, and when you make huge mistakes.
This kind of grace makes all the difference in the world when it's coming from God, through you, to your children.
