Do not be afraid to work; do not be afraid to sacrifice your time to the Lord!
«But he who had received one went and dug in the ground, and hid his lord’s money» (Mathew, 25:18).
This person received some money from his master and he hid it. Please, notice these words ‘money from his master’. He knew that what he had received did not belong to him; it belonged to his master. And he made a conscious decision to hide the treasure his master had given him.
