This study examines the transformation of the concept of human labor from ancient perceptions of a curse and punishment to a radical re-evaluation in the teachings of Jesus Christ. While archaic and mythical conceptions viewed work as a necessary evil and a painful burden that separated man from the service of God, Jesus overcame this dualism. The author analyzes how Jesus relativized cultic prescriptions, such as the observance of the Sabbath, and prioritized service to one's neighbor. Work ceases to be understood as a profane activity opposed to spiritual life; instead, it becomes an integral part of it. In this context, true worship is identified with concrete assistance to the needy, the weak, and the oppressed. The text emphasizes that faith inspired by Jesus is an active, worldly faith where working for others without expectation of reward represents the highest form of ethical and religious life, providing human existence with new meaning and justification.
