Why does the Lord correct us when we sin?

Lord, we have sinned against you, time and time again, and we know that it is because of our fear of you that you correct us, and enters into judgment with us,  we know that whom the Lord loves, he corrects, so correct us Lord with justice, be merciful to us and pardon us, so that one day you will delight in us again and make us joyful and restores us to righteousness. Amen!
