Goodspeed(i)
7 You must submit to it as discipline. God is dealing with you as his sons. For where is there a son whom his father does not discipline?
8 But if you have none of that discipline which all sons undergo, you are illegitimate children, and not true sons.
9 When our earthly fathers disciplined us we treated them with respect; should we not far more submit to the Father of our spirits, and so have life?
10 For they disciplined us for a short time and as they thought proper, but he does it for our good, to make us share his holiness.
11 Discipline is never pleasant at the time; it is painful; but to those who are trained by it, it afterward yields the peace of character.
