Proverbs 29:22 (ESV)

22 A man of wrath stirs up strife, and one given to anger causes much transgression.

An angry man ignites contention everywhere, not because he makes strong moral stands, but rather because his own heart is constantly in turmoil. Therefore, he disrupts the peace around him with his sinful anger. Only the Prince of Peace can transform such quarrelsome people into peacemakers. By his grace and to his glory there are examples of him quenching the fiery threats of sinners, filling them with his righteous and peaceful Spirit. Remember how the Lord transformed Saul of Tarsus (Acts 9:1–43).
