Oh. snap.

Realization? I sin when I let anger control me. I sin when I think I have the right to be mad because "I'm entitled to feel what I feel" and therefore "I say what I wanna say." I sin when I feel like I have the right to be offended by something that is out of my control because I let it get to me. I let it ruin my day. I let it take over how I'm feeling. I let it control me. 

I guess, the lesson is... things happen. you don't have control over that. However, you do have control in how you react to it and how you feel about it. Reactions and feelings are a choice.

The second part of the verse basically tells you to think first and shut your mouth for awhile. Yes, it tells you to shut it. Don't allow your anger to word vomit things that can be hurtful or words that you don't really mean.

Despite the initial feeling, make up your mind to not let it take over your soul. Don't let it envelope you in negativity and cause you to say mean and rude things (because you're entitled to how you feel so you say what you wanna say).
