Ingratitude is the enemy of our souls, the annihilation of our merits, the scattering of our virtues, the loss of our benefactions. Ingratitude is a burning wind, drying up the fountain of piety, the dew of mercy. Nothing so displeases God, especially in children of grace. For ingratitude obstructs the paths of grace, and where there is ingratitude, grace no longer finds access and has no place. ~St. Bernard
