To console, because we have been consoled

"Blessed be the God and Father of our Lord Jesus Christ, a gentle Father and the God of all consolation, who comforts us in all our sorrows, SO THAT WE CAN OFFER OTHERS, IN THEIR SORROWS, THE CONSOLATION THAT WE HAVE RECEIVED FROM GOD OURSELVES.

"Indeed, as the sufferings of Christ overflow to us, so, through Christ, does our consolation overflow."
2 Corinthians 1:3-5
