The things we cannot change are not necessarily the will of the Almighty. When we pray “Thy will be done,” we do sometimes mean what we can’t change. When we’re adults, we have a fairly good idea what would be the will from on high. The Lord might want us to change some things we thought we couldn’t change.
The young could let us know what some of those things might be. Of course they’re often naive in those things, but they could give us ideas. The Wright brothers were right (pun intended), and they certainly weren’t that old, judging from their photos.
The world has changed indeed. In Western Civilization we no longer run around beheading infidels (with a hunting knife, yet), though that does not mean we are beyond correction. But we can behave beyond such primitive religiosity.
