For as we undergo more of the pain which Christ underwent, so through Christ does our comfort become greater.

But if we are troubled and distressed, it is for your comfort and salvation; or if we are comforted and encouraged, it is for your comfort, which works [in you] when you patiently endure the same sufferings which we experience.

Now I am glad, not that you had sorrow, but that your sorrow was the cause of a change of heart; for yours was a holy sorrow so that you might undergo no loss by us in anything.
