'When absorbed in work, clocks dissolve, mealtimes pass, and we hardly know where we are. The best work does not deplete our energy; it renews it. Jesus knew the experience. As he died on the cross, he exulted, "It is finished," and then delivered his spirit to the Father (19:30). "It is finished" can refer to Jesus' substitutionary atonement, but the phrase normally means just that - something is finished. Jesus finished his redemptive task by laying down his life. When Jesus says, "My food is to do the will of him who sent me," he means that his work invigorates him. Since Jesus is the archetypal human being, we might be able to experience similar results.'
Daniel M Doriani, Work: Its Purpose, Dignity, and Transformation, p.25.
