What does the Bible say about discipline from God?

According to Hebrews 12:5-11, God's discipline is not an indication of His anger, but rather a demonstration of His love. The writer reminds believers that God disciplines those He loves, comparing it to a father's discipline of his children. This discipline is meant for our good—it is designed to help us partake in His holiness. Although it may seem painful at the moment, it produces the peaceful fruit of righteousness for those who are trained by it. Thus, discipline from God is ultimately a means of maturation in faith and character.
