“The devil is in the details” (or fine print). You’ve heard people declare that in exasperation. Are you aware that it belonged to God first? Taking the easy way out and relying on God to bail us out can lead to disaster.
Consider this explanation in Wikipedia:
“The devil is in the detail” is an idiom that refers to a catch or mysterious element hidden in the details, meaning that something might seem simple at a first look but will take more time and effort to complete than expected and derives from the earlier phrase, “God is in the detail” expressing the idea that whatever one does should be done thoroughly; i.e. details are important. (Emphasis added).
