After the first sin, women began to suffer labor pains in bringing forth children (Gn 3:16). Men also began to suffer other pains of labor. To make a living, we had to sweat and suffer (Gn 3:19). Work became a curse. It was a living hell.
Only in Jesus is the curse of work removed. In Jesus, we no longer are slaves forced to work for our human needs. Instead, we are slaves of Christ (Col 3:23-24). We don't have to work for perishable food; we can work for food that lasts unto life eternal (Jn 6:27). Moreover, we don't have to work for everything we get. We can receive grace, that is, a free, unworked-for gift of God.
This life of grace is prefigured by the multiplication of the loaves and fishes. In this miracle, four thousand people got something for nothing (Mk 8:9). They didn't have to work for it. Humanity's slavery to work was superseded by grace from Jesus.
Jesus worked as a carpenter for most of His life, and then became a curse for us by hanging on the tree of the cross (Gal 3:13). Jesus has freed us from the curse of work. Therefore, instead of working in a dead-end job, work for the living, eternal Jesus.
