Riddle me this-
You’re working in the sandwich shop, preparing sandwiches of course, and from time to time you notice the manager let’s a few slices of moldy bread slip by. One day the owners stop by on their way to a meeting and it’s your job to prepare their sandwich order. While doing so you come across a few of those not so premium slices of bread. Do you make the sandwich or not? Maybe a better question would be, would you be worried about it if it wasn’t for the owners?

In this case, the worker, “wanting to gain advantage” and favor with the owners, made sure those sandwiches were perfect.
As for the owners, I bet if they had gotten the same sandwiches their customers were getting, (which is exactly what they should have gotten), you’d see things change pretty quickly. This guy could have wound up being the manager. Instead all he managed to do was schmooze the owners for the moment. In time they saw right through him. God sees right through us every time, right through to our heart’s intentions.

These are inveterate murmurers (grumblers) who complain [of their lot in life], going after their own desires [controlled by their passions]; their talk is boastful and arrogant, [and they claim to] admire men’s persons and pay people flattering compliments to gain advantage. Jude 1:16 (AMP)
