By this all men will know that you are my disciples, if you love one another.”
James 1:19-20
My dear brothers, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, for man’s anger does not bring about the righteous life that God desires.
Proverbs 17:14
Starting a quarrel is like breaching a dam; so drop the matter before a dispute breaks out.
2 Corinthians 12:20
For I am afraid that when I come I may not find you as I want you to be, and you may not find me as you want me to be. I fear that there may be quarreling, jealousy, outbursts of anger, factions, slander, gossip, arrogance and disorder.
