וַיֹּ֣אמֶר מָנ֔וֹחַ עַתָּ֖ה יָבֹ֣א דְבָרֶ֑יךָ מַה־יִּֽהְיֶ֥ה מִשְׁפַּט־הַנַּ֖עַר וּמַעֲשֵֽׂהוּ׃
I rzekł Manoach: Teraz się napewno spełni słowo twoje, ale jakież ma być postępowanie z chłopcem tym i jakież zachowanie się względem niego?

"G-d's work" refers to general things in the world such as extreme heat, or extreme cold, which a person's soul hates, and the fools speculate that their absence would be better than their existence. Alternatively, it refers to G-d's providence with which He guides the world... and in truth, most people are resentful in seeing bad things happening to good people or vice versa, and these fools think that if the world's conduct was in their hands, it would be better and more orderly than it is now..."the various creations which He created for their well-being" - this refers to damaging creatures and poisonous plants, and the like, where, in truth, everything was created perfectly for the well-being of mankind.
