The cooperation makes the person happy and fulfilled
Jesus will hand over everything to the Father, and the crated reality will be included; the loving Father makes us His true sons and daughters, responsible to bring into the world the image of fatherhood and motherhood, to cooperate with a creative work in history, to teach the children to know God as our Father in the experience of love received by parents.
Paul believed to be worthy a hard work by his own hands to serve his and his companions' needs; so he protected the freedom, since “you have been purchased at a price. Do not become slaves to human beings!” (1Cor 7:23).
Although everyone has a task and a responsibility to cooperate for a living, when the consciousness of the truth is weakened by laws and the decisions are based on the consensus of many, the dutiful service becomes a courageous choice in the personal conscience; having to respond to God, the conscience feels the sense of responsibility for the others, for the common good; the true fabric of society stays in the personal dignity and its need to not violate the natural right, even legally.
