"No barrier of coldness and reserve should be allowed to arise between parents and children. Let parents become acquainted with their children, seeking to understand their tastes and dispositions, entering into their feelings, and drawing out what is in their hearts. MH 394.1"
"Train up a child in the way he should go: and when he is old, he will not depart from it."
Proverbs 22:6 speaks of training a child. While EGW's passage doesn't directly mention training, it emphasizes the importance of understanding and connecting with children, which is a necessary component of effective training.
"Parents, let your children see that you love them and will do all in your power to make them happy. If you do so, your necessary restrictions will have far greater weight in their young minds. Rule your children with tenderness and compassion, remembering that “their angels do always behold the face of My Father which is in heaven.” Matthew 18:10 . If you desire the angels to do for your children the work given them of God, co- operate with them by doing your part. MH 394.2"
"Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of my Father which is in heaven."
Ellen White directly references Matthew 18:10 in this passage.
