They who shall enter into [the] joy [of the Lord] shall know what is going on outside in the outer darkness. . .The saints'. . . knowledge, which shall be great, shall keep them acquainted. . .with the eternal sufferings of the lost.
Joie est mon caractere, C'est la faute a Voltaire; Misere est mon trousseau C'est la faute a Rousseau. [Joy is my character, 'Tis the fault of Voltaire; Misery is my trousseau 'Tis the fault of Rousseau.] - Gavroche
Service which is rendered without joy helps neither the servant nor the served. But all other pleasures and possessions pale into nothingness before service which is rendered in a spirit of joy.
Always the seer is a sayer. Somehow his dream is told; somehow he publishes it with solemn joy: sometimes with pencil on canvas, sometimes with chisel on stone, sometimes in towers and aisles of granite, his soul's worship is builded; sometimes in anthems of indefinite music, but clearest and most permanent, in words.
It's always necessary to know when a stage of one's life has ended. If you stubbornly cling to it after the need has passed, you lose the joy and meaning of the rest. And you risk being shaken to your senses by God.
