Theophylact of Bulgaria
The blessing is removed from the unfaithful and idle servant. Anyone who has been entrusted with a gift intended for the upliftment of others yet fails to utilize it for that purpose will forfeit it. Conversely, those who demonstrate greater dedication will also receive a more abundant grace. To the diligent, a greater favor will be bestowed, while from the slothful, what little gift they seem to possess will be taken away. For one who neglects to nurture and develop the gift ultimately loses it, possessing it only in appearance, for their inaction and carelessness lead to its true ruin.
