Anger in the Bible — Is it a Sin?

Anger is not a sin in itself but it can be sinful (for instance, anger "without cause"):
Matthew 5:22

Anger can be provoked:
Colossians 3:21

Anger is exhorted against:
Ephesians 4:31, Colossians 3:8

Anger should not be allowed to become sinful (for instance, giving place to hatred or wrath or any other sin opposed to the fruit of the Spirit (Galatians 5:22-23):
Ephesians 4:26-27
Romans 12:18-21

But anger is justified against wickedness (evil/sin):
Mark 3:5
Matthew 21:12-23
Ephesians 5:11
Galatians 2:11-13

And God's judgement against sinners¹ will be the final expression of his anger against them and thus his justice will be served:
Psalm 7:11
John 3:36
Romans 1:18
Jude 1:14-15
2 Thessalonians 1:3-10


1. That's sinners who do not repent and get converted as God has commanded for salvation (Acts 2:38, Acts 3:19, Acts 17:30-31, Acts 20:20-21). That's people who cannot speak of a transformation by God's power as highlighted in 1 Corinthians 6:9-11 or Titus 3:3-7 for instance, thus remaining on the wrong side of the contrast Jesus will make in the end according to the word in Revelation 22:11-12.
