Thou shalt not steal. Exodus 20:13
I love it when God is short and sweet. I don't really think there are any hidden meanings here, it's just what it says it is, no need to explain, so I won't. I'll just tell a story.
I was chatting with my boss recently, we were talking about the retail business. He said something that struck me. "Show me someone who's worked in retail for over 5 years and I'll show you someone who's stolen, at least one, whether it's an entertainment center or a little jelly candy".
By the world's standards, that's probably true. As Christians, we should have a reputation of being honest, totally and immovably. Working at a store everyday, I have to say, I've been tempted. It's not like I want to go steal some high ticket item. It's more like, "Ok, I just grabbed a water from the cooler, I have to remember to pay for it before I leave today". It would just be so much easier to forget and leave, owing the store only ninety-nine cents, but still owing none the less. Recently, we had a stealing indecent, where an expensive item was being taken on a continual basis. Because of my reputation, I passed scrutiny and continue to work there as a respected employee. Others were not so fortunate.
I don't know how or in what situations you're tempted in this, if at all, but just know, stealing is a sin, no matter how big or small the item is. Being an upright person above reproach is just another way to show the world the light of Christ.
