If work is good, why is it so hard? Why do we struggle to accomplish the things we want to or produce the results that we hope for? Our work in this world has been cursed because of the sin of Adam. Now, through faith and diligence, we must work through difficulty and trial, but it does not mean that it will be fruitless and pointless.
And to Adam he said, ‘Because you have listened to the voice of your wife and have eaten of the tree of which I commanded you, “You shall not eat of it,” cursed is the ground because of you; in pain you shall eat of it all the days of your life; thorns and thistles it shall bring forth for you; and you shall eat the plants of the field. By the sweat of your face you shall eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you shall return.
Genesis 3:17-19
