19 So then, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath; 20 for the wrath of man does not produce the righteousness of God. (James 1:19-20)
The Lord is merciful and gracious, Slow to anger, and abounding in mercy.
The Lord is gracious and full of compassion, Slow to anger and great in mercy.
Proverbs 15:18
A wrathful man stirs up strife, But he who is slow to anger allays contention.
Proverbs 16:32
He who is slow to anger is better than the mighty, And he who rules his spirit than he who takes a city.
The discretion of a man makes him slow to anger, And his glory is to overlook a transgression.
Blessings in Christ Jesus Lord of lords, King of kings!
Last Days of the Age 
In the book of James, I see a foundational principal in my walk with Christ that if I am slow to speak and quick to listen, I will also be slow to wrath. That way if there is any wrath at all, there is a greater possibility it is a righteous wrath that God has established in me and not a wrath of the flesh. I’m sure James had the above proverbs in mind when he wrote his exhortation for us to read today.
