• When a man’s ways please the LORD, he makes even his enemies to be at peace with him. — Proverbs 16:7
  • You keep him in perfect peace whose mind is stayed on you, because he trusts in you. — Isaiah 26:3
  • But I say to you who hear, Love your enemies, do good to those who hate you, bless those who curse you, pray for those who abuse you. — Luke 6:27-28 
  • But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere. — James 3:17 

Or, Christian ethics on any occasion and all occasions. For the follower of Jesus none of these is optional, though none is easy.
