Work is the condition of existence in the material, physical world. If Robinson had not worked, he would have frozen to death and died from hunger, and everybody can see this. So labor is the necessary condition for the spiritual life as well, but not all people can see this clearly, though it is as obvious as the necessity of physical labor for the body.
If any would not work, neither should he eat.
— 2 Thessalonians 3:10
If you are doing nothing, it means you are doing bad things.
Those who do nothing, do bad things. Those who do nothing, have many associates and supporters. The brain of a lazy and idle person is the favorite stopping place of the devil.
Nature does not stop in its development, and it executes all kinds of idleness.
— Johann Wolfgang Von Goethe
You should never be ashamed of any work, even the lowest and dirtiest, but you should be shamed only of the dirtiest moral state, that is the idleness of your body, which is the necessary result of the consumption of the labor of others.
