What does the Bible say about chastening and its effects on believers?

In Hebrews 12, we learn that God chastens every son whom He receives, highlighting this divine discipline as an indicator of our sonship. Though this chastening may not seem pleasant at the moment, it yields the peaceable fruit of righteousness to those who are exercised by it. This means that under God's hand, His people often experience sorrow and pain, yet that refining process is essential for spiritual growth. When we feel the weight of chastisement, it is meant to bring us to a recognition of our sin and lead us toward repentance, ultimately assuring us of God's love and the effectiveness of His grace in our lives.
