Remember that we’ve looked at labor in the context of a fruitful home (Psalm 128:2), and that labor is part of a greater expression of human gifts and talents–an opportunity for rejoicing and the praise of God (128:5-6).
Being humans, sin enters in, even in the sphere of labor:
26. Nor can we overlook the social degeneration brought about by sin, as, for example, when human beings tyrannize nature, selfishly and even brutally ravaging it. This leads to the desertification of the earth (cf. Gen 3:17-19) and those social and economic imbalances denounced by the prophets, beginning with Elijah (cf. 1 Kg 21) and culminating in Jesus’ own words against injustice (cf. Lk 12:13; 16:1-31).
Ravaging of the environment has human consequences; it is not a matter of maintaining natural balance for its own sake.
But generally speaking, sin enters into every human relationship, and we must confront it. Especially within ourselves.
