2 Corinthians 1:6

2 Corinthians 1:6. And whether we be afflicted, it is for your consolation and salvation, which is effectual in the enduring of the same sufferings which we also suffer: or whether we be comforted, it is for your consolation and salvation.

That, is the grand object of Christians, to live for others. When God has helped us to receive both our comforts and our sorrows as matters of trust that we are to take care of for the benefit of our fellow-Christians, then have we learned the lesson which Christ would teach us by them.
