"When obedience becomes our goal, it is no longer an irritation; instead of a stumbling block, it becomes a building block" In order to understand this quote you have to actually think about it. I think we could have used a better example than blocks. It still makes sense though. IT just explains that as long as your obedient for the greater good then you will most likely succeed in life. For example if you are not obedient in school it will be a lot easier for you.
