“Idle hands are the Devil’s workshop.”
Here’s another “Stuff We Say” that has been addressed by someone else better than what I could have. Here’s the link that explains the truth behind “Idle hands are the Devil’s workshop.” While this article is simply their interpretation and opinion, it’s one I agree with.
Truth takeaway: Yes, idle, lazy hands are “the devil’s workshop.” We are to be busy with God’s work. Sure sometimes we need to rest. Sitting around doing nothing will make it easier for us to be doing something we don’t need to be.
(Disclaimer: While I don’t agree with all the answers on Gotquestions.com, this is one subject that I felt they covered very well and truthfully.)
