Trying to teach people to trust God’s discipline and correction without first demonstrating and giving them an appreciation for His love is like expecting someone to pet a growling, barking dog just because you told them it was friendly.
No one is going to accept discipline, being told certain actions are wrong, when they have no comprehension of the love reasoning behind it.
It is the same way with children. Without a foundation of love and trust, they will automatically assume you are trying to limit them when you tell them “no” rather than to protect them out of love. And with their lack of experience-gained wisdom that you have, there is no way they can truly understand your reasoning; it has to come from trust/faith, just as following God’s restrictions come from trust that He had a perfect reason for His guidelines, and it is all for the greater good.
