a quick-tempered person stockpiles stupidity.
—Proverbs 14:29

with hotheads. Bad temper is contagious—don’t get
infected.—Proverbs 22:24-25

desperation in my bones. When someone is duped into
sin, an angry fire burns in my gut.—2 Corinthians 11:29

Since prayer is at the bottom of all this, what I want
mostly is for men to pray—not shaking angry fists at
enemies but raising holy hands to God.—1 Timothy 2:8
