It is not easy for a person to do what is right all the time, even when that person wants to sincerely. And very few, if any, people have a handle on doing things perfectly and never messing up or measuring up.
Even Moses in the Bible, for instance. He did most things right but he did a few things really wrong. Some of the things he did right helped him achieve fame and some of the things he did wrong cost him dearly.
Moses spent a good part of his 120 years of life leading people who were tired of being led through the wilderness. He got fed up with their complaining and one day, it was just too much for him. He either got too "big for his britches" or he decided that he would rather call his own shots.
Either way, it was the wrong decision.
The people were thirsty and no water was in sight. God told Moses to call the people together and to take a rod and speak to the rock. Instead, Moses called the people together, like he was told, and he did take the rod in his hand, but then he changed the order and he hit the rock twice.
Sure enough, the rock spewed forth water.
