Bede

A joyful soul makes a flourishing age, etc. He who rejoices in the inner consolation of the Holy Spirit is also adorned with the flower of good action and expects the fruits of heavenly rewards. But he who is distressed by worldly sorrow, which works death, seems to exercise the fatness of divine charity in the strength of virtues but is unable to truly have it, but rather withers as with dry bones, because he has lost the grace of love in the good deeds he does.
