So Sarah laughed to herself as she thought, "After I am worn out and my lord is old, will I now have this pleasure?"  Then the Lord said to Abraham, "Why did Sarah laugh and say, 'Will I really have a child, now that I am old?'  Is anything too hard for the Lord? I will return to you at the appointed time next year, and Sarah will have a son."  Sarah was afraid, so she lied and said, "I did not laugh." But he said, "Yes, you did laugh." Even if I caused you sorrow by my letter, I do not regret it. Though I did regret it--I see that my letter hurt you, but only for a little while--yet now I am happy, not because you were made sorry, but because your sorrow led you to repentance. For you became sorrowful as God intended and so were not harmed in any way by us. Godly sorrow brings repentance that leads to salvation and leaves no regret, but worldly sorrow brings death. See what this godly sorrow has produced in you: what earnestness, what eagerness to clear yourselves, what indignation, what alarm, what longing, what concern, what readiness to see justice done. At every point you have proved yourselves to be innocent in this matter.
