"When obedience becomes our goal,it is no longer an irritation, instead of a stumbling block, but a building block is written by James P.. It is a little difficult to understand, but it does make sense. If you decide to become obedient, it won'y harm you, but helps you. We always choose wrong decisions to do. Many  people aren't obedient and it isn't a goal to them. Doing wrong actions refers to falling blocks. Being non-obedient means that you have falling blocks, and can have consequences. Imagine a student who was never obedient, so he decides not do his assignments. His parents tell him to do good at school but he never listens. One day, he decides to become obedient. He started to build blocks by being obedient as he did correct choices.
