“A quick-tempered man acts foolishly” (Proverbs 14:17 NKJV).

The man who is easily offended and quick to lose his temper will continually do and say things that make him look foolish. Afterwards, he is often sorry and ashamed, so he repents of his behavior. Yet, his short fuse remains, so that he returns to his folly again and again. The foolish behavior will not stop until his angry temperament is properly dealt with.
 
Anger itself isn’t sin, but uncontrolled anger can lead to sin. So, we must ask the Holy Spirit to give us a long-fuse and self-control, so that Christ rules us, rather than our anger. As the apostle Paul wrote, “Be angry and do not sin; do not let the sun go down on your anger, and give no opportunity to the devil” (Eph. 4:26-27).
