"It's okay to be angry at God when you've been divorced," says Dr. Myles Munroe. "Go to God. Shout at Him. Tell Him you hate it. Tell Him how you feel. God's not upset. He wants you to release that anger, to Him. That's why the Bible says, 'Be angry and sin not.' God wants you to tell Him how you feel so lonely and how you got the bad end of the deal. Lock yourself up in your bedroom and scream at God. You've got to let it out."
This deliberate act of expressing anger in a safe place should be done in private, just between you and God. Use it as a time to really talk out your issues with God. You never have to worry about saying the wrong thing with God.
If you are a parent, you will need to be wise in how you release your anger. Choose a time and place when your children are not present. You don't want to scare them!
It may help to have a regularly scheduled time when you close the door and release your anger in shouts and tears. This will help you train yourself to express anger at appropriate times and in appropriate places; the best time is not when you are immediately reacting to someone's words or actions. As weeks and months go by and you have spent regular time with God expressing your emotions, you will find that the worst of your anger has been effectively spent.
