Ephesians 4:26 Be ye angry, and sin not: let not the sun go down upon your wrath:
4;27 Neither give place to the devil.
In this passage here, it says it is normal and very good to be angry, because if you don't get angered in fact you are not a human being. Lol.
But during your anger, do not sin because the Bible even said it, in your anger, do not sin and do not let the sun goes down on your anger, which means before night falls make sure you forgive and forget what the other party did to you, and also not to allow the devil have a way in your anger because he will definitely use it against you in the nearest future..
