Personal and professional ethics are easier with the gospel. When deciding what to consume or have in your home, just determine if it is virtuous, lovely, or of good report, or praiseworthy. If it isn't, then it won't help you. When dealing with your fellow man, make sure you are honest, true, chaste, benevolent, virtuous, and you are doing good. If you aren't, change. In addition to these guidelines, we have the Light of Christ and the Holy Ghost to help us know when a situation or choice is bad. We do, however, have to listen.
