If I did not believe, if I did not make what is called an act of faith (and each act of faith increases our faith, and our capacity for faith), if I did not have faith that the works of mercy do lighten the sum total of suffering in the world, so that those who are suffering on both sides of this ghastly struggle somehow mysteriously find their pain lifted and some balm of consolation poured on their wounds, if I did not believe these things, the problem of evil would indeed be overwhelming.
