Human anger is never a legitimate tool to promote God’s useful purpose.

Human anger is never a legitimate tool to promote God’s useful purpose.
“For human anger is never a legitimate tool to promote God’s righteous purpose.” James 1: 20(TPT)
Do you ever feel that God is not handling the situation, right?
Yes, you sometimes want to handle some annoying things on God’s behalf?
You have assessed the situation, and you are literarily boiling?
Before you act as the representative of God, remember this:
If you are angry, you cannot do any good thing that God wants to be done.
For anger doesn’t make us useful.
An angry person doesn’t do what God approves of.
Cain was angry because he knew God rejected his offerings.
“Saul was furious with Jonathan and yelled, “You’re no son of mine, you traitor! I know you’ve chosen to be loyal to that son of Jesse. You should be ashamed of yourself! And your own mother should be ashamed that you were ever born.” 1Samuel 20:30
Saul was already out of God’s will because of disobedience.
As humans, you rarely see the complete picture at that moment. 
When you speak out of anger:
You Yell
You use derogatory words. 
You are not right because the anger has beclouded your sense of judgment.
. “anger comes from a clash in perspectives.” 
Before you express yourself in anger, ask yourself whose view are you representing, God or man?
Holy anger of God does exist.
Provocation purely by God’s zeal sometimes occurs.
As Jesus did in correcting the use of the temple. ( Matthew 21)
God’s anger against sin. (Romans 1:18-20)
Human anger is purely from the flesh.
Road rage?
Never let it get hold of you.
Allow them to go away with their provocation.
You will surely get to your destination. 
Before you react to that situation, ask yourself whose perspective are you conveying?
