Anxiety and Frustration

In Jerry Bridges book Respectable Sins, he has a chapter called Anxiety and Frustration. Let me give you a few quotes to chew on...

"The opposite of trust in God is either anxiety or frustration, and Jesus had a lot to say about anxiety." (p.63)

"When you or I say to someone, 'Don't be anxious' or 'Don't be afraid,' we are simply trying to encourage the person, or admonish in a helpful way. But when Jesus (or Paul or Peter, who were writing under divine inspiration) says to us, 'Don't be anxious,' it has the force of a moral command. In other words, it is the moral will of God that we not be anxious. Or to say it more explicitly, anxiety is sin." (p.64)

"Anxiety is sin because it is distrust in God." (p.64) 

"I have come to the conclusion that my anxiety is triggered not so much by a distrust in God as by an unwillingness to submit to and cheerfully accept His agenda for me." (p.65) 

"Worry is a synonym for anxiety." (p.67) 

"Closely akin to anxiety or worry is the sin of frustration. Whereas anxiety involves fear, frustration usually involves being upset or even angry at whatever or whoever is blocking our plans." (p.69) 

"Let me repeat, however, what I have said or implied throughout this chapter. Both anxiety and frustration are sins. They are not to be taken lightly or brushed off as common reactions we have to difficult events in a fallen world. Can you picture Jesus ever being anxious or frustrated? And whatever in our lives is not like Jesus is sin. Granted, we will never achieve complete freedom from anxiety or frustration in this life (at least I don't expect to). But we should never accept them as just part of our temperament any more than we would accept adultery as part of our temperament. Keep in mind that even though anxiety and frustration may not be as serious as adultery, they are still sins. And all sin is serious in the eyes of a Holy God." (p.70)
