“The wicked flee when no one pursues,but the righteous are bold as a lion.” Prov 28:1
Evil people are often paranoid. Unfortunately, many Christians are as well. Fear is quite unbecoming in a believer because it is contradictory to his identity. Fear is the basic sin of unbelief.
The righteous are bold! What is it about righteousness that requires an absence of fear? A righteous person understands what is important. He understands that pleasing God and doing right is much more important than pleasing others or self. He also has a deep confidence that righteousness is ultimately best for himself and others anyway. That is what it takes to be righteous. That is also what it takes to be bold, to do what is right in the face of hatred and self denial.
