Quick Response Is Important

Recently, when Jeshua was busy with his toys and stuff, he didn't respond to my voice; at least not until I called him by name for more than six times.

I'm not very happy with that.

I have decided to discipline him in this area when he grows slightly older (to understand my reason), if he doesn't respond to my call promptly. 

This is crucial. If he doesn't respond to his father promptly, he won't respond to God promptly when He calls him.

Delayed obedience is not obedience.
