Hebrews 12:7

If ye endure chastening. See on verses 3, 5. Textual evidence attests (cf. p. 10) the reading “endure unto chastening.” According to this reading these words constitute an imperative sentence, an admonition based on the principle stated in verse 6. Too often we pray for victory over particular sins, only to find that God answers our prayers by permitting circumstances that will develop strength at the very points where we are weak. Let us recognize God’s answer to our prayers, and not falter. Let us courageously and submissively “endure unto chastening.”

As with sons. Parents are usually reluctant to administer discipline to children not their own, but a wise parent does not hesitate to discipline his own children when they need it. Discipline is the prerogative, duty, and responsibility of parents. Thus, in a sense, the administration of discipline is evidence of parenthood.

What son? No child is born with a mature character, and every child therefore needs discipline in order that he may fill a useful place in the world and be a credit to the family.
