Hebrews Chapter 12 : 3 - 11 NASB
3For consider Him who has endured such hostility by sinners against Himself, so that you will not grow weary and lose heart.
4You have not yet resisted to the point of shedding blood in your striving against sin;
5and you have forgotten the exhortation which is addressed to you as sons,
“My son, do not regard lightly the discipline of the Lord,
Nor faint when you are reproved by Him;
6 For those whom the Lord loves He disciplines,
And He scourges every son whom He receives.”
7It is for discipline that you endure; God deals with you as with sons; for what son is there whom his father does not discipline?
8But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons.
9Furthermore, we had earthly fathers to discipline us, and we respected them; shall we not much rather be subject to the Father of spirits,
10For they disciplined us for a short time as seemed best to them, but He disciplines us for our good, so that we may share His holiness.
11All discipline for the moment seems not to be joyful, but sorrowful; yet to those who have been trained by it, afterwards it yields
the peaceful fruit of righteousness.
