Which is precisely why the New Testament puts such emphasis on repenting changing the way you think. I have a book that is a farce on life in corporate America. It gives many examples of how to make the corporate system work to your advantage while doing as little actual work as possible. Most of the examples are both funny and sad. Such activities demonstrate a pathetic absence of integrity.
Integrity is an attitude that motivates certain behavior.
It will cause you to show up for work on time every day, even when you know no one will notice whether you are late. It will cause you to take care of personal matters on personal time, rather than at work. For example, using your office computer for personal e-mail is usually a violation of your integrity as well as company policy. Yeah, but it just takes twenty minutes a day. Otherwise, your reaction reveals your lack of integrity.
