In Galatians 5 we read about the fruit of gripping.

But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, (23) gentleness and self-control. Against such things there is no law. Gal 5:22-23

The Greek word for self-control means “to get a grip on oneself.” Simply put, Discipline is extreme self-control.
