My son, do not regard lightly the discipline of the Lord, not faint when you are reproved by Him; For those whom the Lord loves He disciplines. Hebrew 12:5-6
Discipline from the Lord is a sign from Him of love and caring. His correction comes from love and in the long run it is best for all of us. As we grow up in Christ, His discipline is necessary. It may not seem joyful at the moment, but if we accept it, learn from it, and don't faint. it will pay off. Our Father really does know best.
