Why is the chastening of the Lord viewed as a blessing?

Hebrews 12:6 states, 'For whom the Lord loveth he chasteneth.' Chastening serves to correct and guide God’s children, leading them back to righteousness. As believers endure trials and corrective experiences, they grow closer to God's heart and recognize His love in their lives. When the Lord's discipline is embraced positively, it leads to genuine happiness, understanding that it is an affirmation of their sonship in Christ. Hence, even in correction, there is joy rooted in the assurance of God's fatherly love.
