'Discipline' in the Bible

And you have forgotten the exhortation that addresses you as sons:My son, do not take the Lord’s discipline lightlyor faint when you are reproved by Him,

Endure suffering as discipline: God is dealing with you as sons. For what son is there that a father does not discipline?

But if you are without discipline—which all receive—then you are illegitimate children and not sons.

Furthermore, we had natural fathers discipline us, and we respected them. Shouldn’t we submit even more to the Father of spirits and live?

No discipline seems enjoyable at the time, but painful. Later on, however, it yields the fruit of peace and righteousness to those who have been trained by it.
