"For whom the Lord love He reproves, even as a father the son in whom he delights."
Proverbs 3:12

"Behold, how happy is the man whom God reproves, so do not despise the discipline of the Almighty. For He inflicts pain, and gives relief; He wounds, and His hands also heal."
Job 5:17-18

"Blessed is the man whom You chasten, O Lord, and whom You teach out of Your law; that You may grant him relief from the days of adversity, until a pit is dug for the wicked."
Psalm 94:12-13

"But when we are judged, we are disciplined by the Lord so that we will not be condemned along with the world."
1 Corinthians 11:32

"Therefore we do not lose heart, but though our outer man is decaying, yet our inner man is being renewed day by day. For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison."
2 Corinthians 4:16-17

"My son, do not regard lightly the discipline of the Lord, nor faint when you are reproved by Him, for those whom the Lord loves He disciplines, and He scourges every son whom He receives. It is for discipline that you endure; God deals with you as with sons; for what son is there whom his father does not discipline? ... Furthermore, we had earthly fathers to discipline us, and we respected them; shall we not much rather be subject to the Father of spirits, and live? For 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. All 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."
Hebrews 12:5-11
