"If we do what's right, we have no need to fear."- Evan Stephens

What this quote is saying is that you don't need to fear if you are always doing what's right. If you do wrong, you will feel fear of being caught. For example, doing wrong like breaking something will have you feel nervous of what's gonna happen next. If you break a law, you will fear of being arrested. Anything bad thing you do, you will most likely have fear of  being caught or punished. But if you do good, you won't have to live in fear. For example if you follow the law, you won't have the fear of being punished. If you're careful of what you do, you have the fear of anything bad happening to you.
