'Anger' in the Bible

For God's anger is being revealed from Heaven against all impiety and against the iniquity of men who through iniquity suppress the truth. God is angry:

The fact is that in the stubbornness of your impenitent heart you are treasuring up against yourself anger on the day of Anger--the day when the righteousness of God's judgements will stand revealed.

while on the other hand upon the self-willed who disobey the truth and obey unrighteousness will fall anger and fury, affliction and awful distress,

If therefore we have now been pronounced free from guilt through His blood, much more shall we be delivered from God's anger through Him.

And what if God, while choosing to make manifest the terrors of His anger and to show what is possible with Him, has yet borne with long-forbearing patience with the subjects of His anger who stand ready for destruction,

Do not be revengeful, my dear friends, but give way before anger; for it is written, "'Revenge belongs to Me: I will pay back,' says the Lord."
