Can you really be angry without sinning? Aren't there wrong things to be angry about? For example, what if my brother borrowed money and never paid me back and I needed to pay a bill, well then I think anger might be justified. But, what if he simply did something that is just really annoying, but not something he realizes is annoying. Then, do I have a right to be angry? So, is anger ever justified and if so in what situations and why? Any Scripture on this?
