Dear Friends of the Cross, we are all sinners; there is not one of us who has not deserved hell, and I more than anyone. Our offences have to be punished either in this world or in the next. If we suffer for them now, we shall not suffer for them after death. If we willingly accept punishment for them, this punishment will be an act of God's love; for it is mercy which holds sway and chastises in this world, and not strict justice. This punishment will be light and temporary, accompanied by consolation and merit, and followed by rewards both here and in eternity.
--St. Louis de Montfort, Letter to the Friends of the Cross
