Sin is any deliberate action, attitude, or thought that goes against God. You may think of sin as an obvious act, such as murder, adultery, or theft. Although that's true, sin is also wrongdoing that's far subtler and even unnoticeable at times, such as pride, envy, or even worry. Sin includes both things you shouldn't have done, but did (sins of commission) and things you should've done, but didn't (sins of omission).
