Be ye angry, and sin not: let not the sun go down upon your wrath: (Ephesians 4:26 KJV)
People are bound to upset you.
This is a fact that has been evident since the very first family was placed on earth. Cain was upset with Abel because God accepted Abel's offering and rejected his. Joseph's brother's were upset with Joseph simply because he was a dreamer, very optimistic and HOPEFUL.
Things haven't changed much since then. People will get upset with you no matter what you do. Good or Bad. Strangely enough that's life!
There is one piece of advice I want to share. Don't take on people like that. Don't let anyone upset you. When they get you a bit angry, stay calm, act professional and talk with Jesus instead of to them. I believe one of the reasons we probably have such a high rate of persons suffering from high blood pressure and stress, is simply because we let people upset us and cause us pain too easily.
In reading through many of the accounts in the Bible, we can learn many lessons from Jesus' responses. Many times when he was challenged and accused, he didn't say a thing. Even when he was on trial just before he was to lay down his life for our sins, he didn't say anything.
Isaiah 53:7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
When ever people try to upset you and you get a bit angry, simply take a cool walk away from the situation and talk with Jesus as you go. This isn't being coward. It's being wise. Sometimes, even when you are in the right, simply say you're sorry and move on. There is nothing wrong with that too.
I'm so sorry. . . .Look how easy that is to say. Friend, if any of my actions in the past or in the future have upset you or will upset, let me use this forum now to publicly say - I AM SORRY!
If we let every situation upset us and get us angry, we'll have NO TIME to keep our eyes on pursuing our dreams and staying HOPEFUL. That's a trick of the enemy! Don't let him succeed and Don't let people upset you!
Deal? - Deal!
