Be angry but do not sin; do not let the sun go down on your anger,
Ephesians 4:26 ESV
In basketball you see this play over and over. A guy gets out in the open court. He makes a move and throws up a shot. It doesn’t go in and there isn’t a call. The guy gets angry — he might be angry at himself for making a dumb move or missing an easy shot, he might be angry at a teammate for not getting open like he thought he should have, or he might be angry that the ref didn’t call a foul.
It doesn’t really matter why he is angry. The ball is going the other way and he is going to race back down the court and do something stupid. The refs have seen it happen over and over, and it is an easy call.
You could say, be angry, but don’t do something stupid in your anger. That is the first step — get back under control. Then after the game figure out why you are angry — first clue, if you are out of control you probably won’t get a favorable call whatever contact there is on a play. Whatever it is, figure out why you are angry, then let the anger go.
I’m not saying to forget about the play — but get the anger out of it and come up with a solution for the next time you are in that situation.
