Naturally, you're a parent with good manners and liberal in the use of please and thank-you. Courteous parents have a head-start successfully controlling their children. I'm believing that your children feel accepted as they are, for what they are. That's giving due respect to each child. I assume that you understand the principle of earning the right to be heard.
Parental authority is strengthened by a genuine spirit of meekness.
I expect that you have taken the time to establish a personal relationship with each of your family members. When your life is characterized by moral excellence and integrity, the words you speak will have authority. Your authority is eroded when your children see you viewing questionable T.V. and reading two bit novels. Hiding goods at the border and pulling the wool over your spouses eyes, diminishes the authority of your words. When the above seven character traits are a reality in your life, your life carries spiritual authority and your words carry weight.
