The real reason parents spank isn't because they believe God commands it.
The real reason parents spank isn't because they believe they were spanked and turned out OK.
The real reason parents spank isn't because they believe it is the right thing to do.
The real reason parents spank is because their own parents...over the course of many years using example and repetition...taught them how to handle situations in which they need a smaller/weaker person to do what they want...and they are still imitating their parents. Through example and repetition they have been trained and now that they are old they can't depart from it because they don't know any other way to do it.
And, the real reason parents spank is because it is a heck of a lot easier to "receive that free cookie at the grocery store" and make someone else accountable for etiquette and politeness, "What do you saaaaay kids?" than hold yourself accountable to set the example yourself repeatedly and you say, "Thank you!" so that the children become polite by imitating you.
Therefore be imitators of God, as beloved children
If your children are misbehaving they don't need a spanking...they need a better example to imitate...
Parents, should be able to this to your children in all things...
"Be imitators of me, just as I also am of Christ."
1 Cor. 11:1
