27 The concept of work can turn into an exaggerated mystique. Yet, for all that, it is something willed and approved by God. Fashioned in the image of his Creator, "man must cooperate with Him in completing the work of creation and engraving on the earth the spiritual imprint which he himself has received." (25) God gave man intelligence, sensitivity and the power of thought—tools with which to finish and perfect the work He began. Every worker is, to some extent, a creator—be he artist, craftsman, executive, laborer or farmer. Bent over a material that resists his efforts, the worker leaves his imprint on it, at the same time developing his own powers of persistence, inventiveness and concentration. Further, when work is done in common—when hope, hardship, ambition and joy are shared—it brings together and firmly unites the wills, minds and hearts of men. In its accomplishment, men find themselves to be brothers. (29)
