Proverbs 23:13-14 Do not withhold discipline from a child; if you strike him with a rod, he will not die. If you strike him with the rod, you will save his soul from Sheol.
When it comes to physical punishment, the Scriptures address the parents and not the child. It assumes we’d rather not discipline. It assumes we have a hard time reconciling God’s will with pain.
Why do we do it? Whatever grows must be trained.
How do we do it? We use a measured application appropriate to the situation.
What is the goal? Compliance? No. It’s a loving safeguard against death.
Correcting a child will save them from a Sheol of consequences.
In reality, the ultimate child abuse is letting them do whatever they want.
