Deuteronomy 8:16

Psalms 94:12-14

94:12 How blessed is the one whom you instruct, O Lord,

the one whom you teach from your law,

he does not abandon the nation that belongs to him.

Psalms 119:67

Hebrews 12:5-10

12:5 And have you forgotten the exhortation addressed to you as sons?

“My son, do not scorn the Lord’s discipline

or give up when he corrects you.

12:6 “For the Lord disciplines the one he loves and chastises every son he accepts.”

12:7 Endure your suffering as discipline; God is treating you as sons. For what son is there that a father does not discipline? 12:8 But if you do not experience discipline, something all sons have shared in, then you are illegitimate and are not sons. 12:9 Besides, we have experienced discipline from our earthly fathers and we respected them; shall we not submit ourselves all the more to the Father of spirits and receive life? 12:10 For they disciplined us for a little while as seemed good to them, but he does so for our benefit, that we may share his holiness.

Revelation 3:19

3:19 All those I love, I rebuke and discipline. So be earnest and repent!
