One of the things that all three sources have in common is they recognize the creep of the usage of "screens." All three recognize how important "screens" are for communication and information gathering these days. However, there has to be distance. The ancient word "sabbath" continues to be used.
The Sabbath is given by God as a command because we have to be told, ordered really, to stop and rest. It is within our nature to keep going until we burn ourselves out. Back in the day it was through physical labor. Now, the new danger is through constant use of our screens. This "FOMO" or Fear of missing out does nothing but wear us out and heighten our anxiety.
DeYoung is a Christian. I don't know about Powers or King. But, what all three (and lots of others) alert us to is that we need to observe that third commandment for our own sakes. If we don't we die.
